Prior to v1.8.1.1, with:
git init
echo content >foo &&
mkdir subdir &&
echo content >subdir/bar &&
echo "subdir export-ignore" >.gitattributes
git add . &&
git commit -m one &&
git archive HEAD | tar tf -
the resulting archive would contain only "foo" and ".gitattributes",
not subdir. This was broken with a recent change that intended to
allow "subdir/ export-ignore" to also exclude the directory, but
instead ended up _requiring_ the trailing slash by mistake.
A pattern "subdir" should match any path "subdir", whether it is a
directory or a non-directory. A pattern "subdir/" insists that a
path "subdir" must be a directory for it to match.
This patch adds test not just for this simple case, but also for
deeper cross-directory cases, as well as cases with wildcards.

This function takes two counted strings: a <pattern, patternlen> pair
and a <pathname, pathlen> pair. But we end up feeding the result to
fnmatch, which expects NUL-terminated strings.
We can fix this by calling the fnmatch_icase_mem function, which
handles re-allocating into a NUL-terminated string if necessary.
While we're at it, we can avoid even calling fnmatch in some cases. In
addition to patternlen, we get "prefix", the size of the pattern that
contains no wildcard characters. We do a straight match of the prefix
part first, and then use fnmatch to cover the rest. But if there are
no wildcards in the pattern at all, we do not even need to call
fnmatch; we would simply be comparing two empty strings.

If we receive a pattern that starts with "/", we shift it
forward to avoid looking at the "/" part. Since the prefix
and patternlen parameters are counts of what is in the
pattern, we must decrement them as we increment the pointer.
We remembered to handle prefix, but not patternlen. This
didn't cause any bugs, though, because the patternlen
parameter is not actually used. Since it will be used in
future patches, let's correct this oversight.

The function takes two counted strings (<basename, basenamelen> and
<pattern, patternlen>) as parameters, together with prefix (the
length of the prefix in pattern that is to be matched literally
without globbing against the basename) and EXC_* flags that tells it
how to match the pattern against the basename.
However, it did not pay attention to the length of these counted
strings. Update them to do the following:
* When the entire pattern is to be matched literally, the pattern
matches the basename only when the lengths of them are the same,
and they match up to that length.
* When the pattern is "*" followed by a string to be matched
literally, make sure that the basenamelen is equal or longer than
the "literal" part of the pattern, and the tail of the basename
string matches that literal part.
* Otherwise, use the new fnmatch_icase_mem helper to make
sure we only lookmake sure we use only look at the
counted part of the strings. Because these counted strings are
full strings most of the time, we check for termination
to avoid unnecessary allocation.

The function is given a string that ends with a slash to signal that
the path is a directory to make sure that a pattern that ends with a
slash (i.e. MUSTBEDIR) can tell directories and non-directories
apart. However, the pattern itself (pat->pattern and
pat->patternlen) that came from such a MUSTBEDIR pattern is
represented as a string that ends with a slash, but patternlen does
not count that trailing slash. A MUSTBEDIR pattern "element/" is
represented as a counted string <"element/", 7> and this must match
match pathname "element/".
Because match_basename() and match_pathname() want to see pathname
"element" to match against the pattern <"element/", 7>, reduce the
length of the path to exclude the trailing slash when calling
these functions.

Convert the loop in score_trees() to tree_entry(). The code becomes
shorter and simpler because the calls to update_tree_entry() are not
needed any more.
Another benefit is that we need less variables to track the current
tree entries; as a side-effect of that the compiler has an easier
job figuring out the control flow and thus can avoid false warnings
about uninitialized variables.
Using struct name_entry also allows the use of tree_entry_len() for
finding the path length instead of strlen(), which may be slightly
more efficient.
Also unify the handling of missing entries in one of the two trees
(i.e. added or removed files): Just set cmp appropriately first, no
matter if we ran off the end of a tree or if we actually have two
entries to compare, and check its value a bit later without
duplicating the handler code.

Logic in still_interesting function allows to stop the commits
traversing if the oldest processed commit is not older then the
youngest commit on the list to process and the list contains only
commits marked as not interesting ones. It can be premature when dealing
with a set of coequal commits. For example git rev-list A^! --not B
provides wrong answer if all commits in the range A..B had the same
commit time and there are more then 7 of them.
To fix this problem the relevant part of the logic in still_interesting
is changed to: the walk can be stopped if the oldest processed commit is
younger then the youngest commit on the list to processed.

There are two uses of the "left" and "right" commit variables that
make it hard to be sure what values they have (both for the reader,
and for gcc, which wrongly complains that they might be used
uninitialized).
The function starts with a cascading if statement, checking that the
input sha1s exist, and finally working up to preparing a revision
walk. We only prepare the walk if the cascading conditional did not
find any problems, which we check by seeing whether it set the
"message" variable or not. It's simpler and more obvious to just add
a condition to the end of the cascade.
Later, we check the same "message" variable when deciding whether to
clear commit marks on the left/right commits; if it is set, we
presumably never started the walk. This is wrong, though; we might
have started the walk and munged commit flags, only to encounter an
error afterwards. We should always clear the flags on left/right if
they exist, whether the walk was successful or not.

Originally update-pre-post-images could assume that any whitespace
fixing will make the result only shorter by unexpanding runs of
leading SPs into HTs and removing trailing whitespaces at the end of
lines. Updating the post-image we read from the patch to match the
actual result can be performed in-place under this assumption.
These days, however, we have tab-in-indent (aka Python) rule whose
result can be longer than the original, and we do need to allocate
a larger buffer than the input and replace the result.
Fortunately the support for lengthening rewrite was already added
when we began supporting "match while ignoring whitespace
differences" mode in 86c91f9179 (git apply: option to ignore
whitespace differences, 2009-08-04). We only need to correctly
count the number of bytes necessary to hold the updated result and
tell the function to allocate a new buffer.

In wt_status_print_change_data, we accept a change_type flag
that is meant to be either WT_STATUS_UPDATED or
WT_STATUS_CHANGED. We then switch() on this value to set
the local variable "status" for each case, but do not
provide a fallback "default" label to the switch statement.
As a result, the compiler realizes that "status" might be
unset, and complains with a warning. To silence this
warning, we use the "int status = status" trick. This is
correct with the current code, as all callers provide one of
the two expected change_type flags. However, it's also a
maintenance trap, as there is nothing to prevent future
callers from passing another flag, nor to document this
assumption.
Instead of using the "x = x" hack, let's handle the default
case in the switch() statement with a die("BUG"). That tells
the compiler and any readers of the code exactly what the
function's input assumptions are.
We could also convert the flag to an enum, which would
provide a compile-time check on the function input. However,
since these flags are part of a larger enum, that would make
the code unnecessarily complex (we would have to make a new
enum with just the two flags, and then convert it to the old
enum for passing to sub-functions).

When we read a fast-import line like:
M 100644 :1 foo.c
we point the local object_entry variable "oe" to the object
named by the mark ":1". When the input uses the "inline"
construct, however, we do not have such an object_entry.
The current code is careful not to access "oe" in the inline
case, but we can make the assumption even more obvious (and
catch violations of it) by setting oe to NULL and adding a
comment. As a bonus, this also squelches an over-zealous gcc
-Wuninitialized warning, which means we can drop the "oe =
oe" initialization hack.
