0d1d6e50cf t/t7003: replace \t with literal tab in sed expression
The sed utilities on IRIX and Solaris do not interpret the sequence '\t'
to mean a tab character;  they read a literal character 't'.  So, use a
literal tab instead.

7e7db5e452 fast-import: export correctly marks larger than 2^20-1
dump_marks_helper() has a bug when dumping marks larger than 2^20-1,
i.e., when the sparse array has more than two levels.  The bug was
that the 'base' counter was being shifted by 20 bits at level 3, and
then again by 10 bits at level 2, rather than a total shift of 20 bits
in this argument to the recursive call:

  (base + k) << m->shift

There are two ways to fix this correctly, the elegant:

  (base + k) << 10

and the one I chose due to edit distance:

  base + (k << m->shift)

5536934239 t/lib-git-svn.sh: use $PERL_PATH for perl, not perl from $PATH
Change the git-svn tests to use $PERL_PATH, not the "perl" in $PATH.

Using perl in $PATH was added by Sam Vilain in v1.6.6-rc0~95^2~3,
Philippe Bruhat introduced $PERL_PATH to the test suite in
v1.6.6-rc0~9^2, but the lib-git-svn.sh tests weren't updated to use
the new convention.

This resulted in the git-svn tests always being skipped on my
system. My /usr/bin/perl has access to SVN::Core and SVN::Repos, but
the perl in my $PATH does not.

d8faea9d18 diff: strip extra "/" when stripping prefix
There are two ways a user might want to use "diff --relative":

  1. For a file in a directory, like "subdir/file", the user
     can use "--relative=subdir/" to strip the directory.

  2. To strip part of a filename, like "foo-10", they can
     use "--relative=foo-".

We currently handle both of those situations. However, if the user passes
"--relative=subdir" (without the trailing slash), we produce inconsistent
results. For the unified diff format, we collapse the double-slash of
"a//file" correctly into "a/file". But for other formats (raw, stat,
name-status), we end up with "/file".

We can do what the user means here and strip the extra "/" (and only a
slash).  We are not hurting any existing users of (2) above with this
behavior change because the existing output for this case was nonsensical.

3c8710aeaa t7003: fix subdirectory-filter test
The test would not fail if the filtering failed to do anything, since
in

  test -z "$(git diff HEAD directorymoved:newsubdir)"'

'directorymoved:newsubdir' is not valid, so git-diff fails without
printing anything on stdout.  But then the exit status of git-diff is
lost, whereas test -z "" succeeds.

Use 'git diff --exit-code' instead, which does the right thing and has
the added bonus of showing the differences if there are any.

25e9325040 Fix git rebase --continue to work with touched files
When performing a non-interactive rebase, sometimes
"git rebase --continue" will fail if an unmodified file is
touched in the working directory:

    You must edit all merge conflicts and then
    mark them as resolved using git add

This is caused by "git diff-files" reporting a difference
between the index and the filesystem:

    :100644 100644 d00491...... 000000...... M	file

The fix is to run "git update-index --refresh" before
"git diff-files" as is done in git-rebase--interactive.

c1e02b2b38 t3700-add: fix dependence on stdout and stderr buffering
One test case checked the stdout and stderr of 'git add' by constructing a
single 'expect' file that contained both streams. But when the command
runs, the order of stdout and stderr output is unpredictable because it
depends on how the streams are buffered. At least on Windows, the buffering
is different from what the test case expected. Hence, check the two output
texts separately.

938791cd01 git-rebase--interactive.sh: use printf instead of echo to print commit message
On systems with an echo which defaults to the XSI-conformant behavior
(Solaris, or others using Ksh), echo will interpret certain backslashed
characters as control sequences.  This can cause a problem for interactive
rebase when it is used to rebase commits whose commit "subject" (the first
line) contains any of these backslashed sequences.  In this case, echo will
substitute the control sequence for the backslashed characters and either
the rebased commit message will differ from the original, or the rebase
process will fail.  Neither is desirable.

So work around this issue by replacing the echo statements used to print
out portions of the commit message, with printf.

Also, add a test to test for this breakage.

77b5be2aba t/{t5541,lib-httpd}: replace problematic '!()' notation with test_must_fail
The '!()' notation is interpreted as a pattern-list on Ksh.  The Ksh man
page describe it as follows:

   !(pattern-list)
      Matches anything except one of the given patterns.

Ksh performs a file glob using the pattern-list and then tries to execute
the first file in the list.  If a space is added between the '!' and the
open parens, then Ksh will not interpret it as a pattern list, but in this
case, it is preferred to use test_must_fail, so lets do so.

460d562eab t/t3700: convert two uses of negation operator '!' to use test_must_fail
These two lines use the negation '!' operator to negate the result of a
simple command.  Since these commands do not contain any pipes or other
complexities, the test_must_fail function can be used and is preferred
since it will additionally detect termination due to a signal.

This was noticed because the second use of '!' does not include a space
between the '!' and the opening parens.  Ksh interprets this as follows:

   !(pattern-list)
      Matches anything except one of the given patterns.

Ksh performs a file glob using the pattern-list and then tries to execute

030149a4dc git --paginate: paginate external commands again
73e25e7c (git --paginate: do not commit pager choice too early,
2010-06-26) failed to take some cases into account.

1b. Builtins that do not use RUN_SETUP (like git config) do
    not find GIT_DIR set correctly when the pager is launched
    from run_builtin().  So the core.pager configuration is
    not honored from subdirectories of the toplevel for them.

4a. External git commands (like git request-pull) relied on the
    early pager launch to take care of handling the -p option.
    Ever since 73e25e7c, they do not honor the -p option at all.

4b. Commands invoked through ! aliases (like ls) were also relying
    on the early pager launch.

Fix (4a) by launching the pager (if requested) before running such a
“dashed external”.  For simplicity, this still does not search for a
.git directory before running the external command; when run from a
subdirectory of the toplevel, therefore, the “[core] pager”
configuration is still not honored.

Fix (4b) by launching pager if requested before carrying out such an
alias.  Actually doing this has no effect, since the pager (if any)
would have already been launched in a failed attempt to try a
dashed external first.  The choice-of-pager-not-honored-from-
subdirectory bug still applies here, too.

(1b) is not a regression.  There is no need to fix it yet.

as the path should be the same among all the stages no matter which
sides are involved in the merge.

e8344e8666 tests: Use skip_all=* to skip tests
Change tests to skip with skip_all=* + test_done instead of using say
+ test_done.

This is a follow-up to "tests: Skip tests in a way that makes sense
under TAP" (fadb5156e4). I missed these cases when prepearing that
patch, hopefully this is all of them.

b1f47514f2 Fix "read-tree -m A B" priming the cache-tree
In 456156d a shortcut to priming the index tree reference was
introduced, but the justification for it was completely bogus.

"read-tree -m A B" is to take the index (and the working tree)
that is largely based on (but does not have to match exactly) A
and update it to B, while carrying the local change that does
not overlap the difference between A and B, so there is no reason
to expect that the resulting index should match the tree B.

Noticed and test provided by Heiko Voigt.
