If "git am" fails to apply something, the end user may need to know
where to find the patch that failed to apply, so that the user can
do other things (e.g. trying "GNU patch" on it, running "diffstat"
to see what it tried to change, etc.) The input to "am" may have
contained more than one patch, or the message may have been MIME
encoded, and knowing what the user fed to "am" does not help very
much for this purpose.

learned where to look to squelch this message.

Due to the way "git diff --no-index" is bolted onto by touching the
low level code that is shared with the rest of the "git diff" code,
even though it has to work in a very different way, any comparison
that involves a file "-" at the root level incorrectly tried to read
from the standard input. This cleans up the no-index codepath
further to remove code that reads from the standard input from the
core side, which is never necessary when git is running its usual
diff operation.

During a revision traversal in which --max-count has been
specified, we decrement a counter for each revision returned
by get_revision. When it hits 0, we typically return NULL
(the exception being if we still have boundary commits to
show).
However, before we check the counter, we call get_revision_1
to get the next commit. This might involve looking at a
large number of commits if we have restricted the traversal
(e.g., we might traverse until we find the next commit whose
diff actually matches a pathspec).
There's no need to make this get_revision_1 call when our
counter runs out. If we are not in --boundary mode, we will
just throw away the result and immediately return NULL. If
we are in --boundary mode, then we will still throw away the
result, and then start showing the boundary commits.
However, as git_revision_1 does not impact the boundary
list, it should not have an impact.
In most cases, avoiding this work will not be especially
noticeable. However, in some cases, it can make a big
difference:
[before]
$ time git rev-list -1 origin Documentation/RelNotes/1.7.11.2.txt
8d141a1d56
real 0m0.301s
user 0m0.280s
sys 0m0.016s
[after]
$ time git rev-list -1 origin Documentation/RelNotes/1.7.11.2.txt
8d141a1d56
real 0m0.010s
user 0m0.008s
sys 0m0.000s
Note that the output is produced almost instantaneously in
the first case, and then git uselessly spends a long time
looking for the next commit to touch that file (but there
isn't one, and we traverse all the way down to the roots).

Since 69c3051 (submodules: refactor computation of relative gitdir path)
cloning a submodule recursively fails for nested submodules when a
symbolic link is part of the path to the work tree of the superproject.
This happens when module_clone() tries to find the relative paths between
the work tree and the git dir. When a symbolic link in current $PWD points
to a directory that is at a different level, then determining the number
of "../" needed to traverse to the superproject's work tree leads to a
wrong result.
As there is no portable way to say "pwd -P", use cd_to_toplevel to remove
the link from $PWD, which fixes this problem.
A test for this issue has been added to t7406.

use the length.

When the unpack_data function is given a consume() callback,
it unpacks only 64K of the input at a time, feeding it to
git_inflate along with a 64K output buffer. However,
because we are inflating, there is a good chance that the
output buffer will fill before consuming all of the input.
In this case, we need to loop on git_inflate until we have
fed the whole input buffer, feeding each chunk of output to
the consume buffer.
The current code does not do this, and as a result, will
fail the loop condition and trigger a fatal "serious inflate
inconsistency" error in this case.
While we're rearranging the loop, let's get rid of the
extra last_out pointer. It is meant to point to the
beginning of the buffer that we feed to git_inflate, but in
practice this is always the beginning of our same 64K
buffer, because:
1. At the beginning of the loop, we are feeding the
buffer.
2. At the end of the loop, if we are using a consume()
function, we reset git_inflate's pointer to the
beginning of the buffer. If we are not using a
consume() function, then we do not care about the value
of last_out at all.
