Traditional "opportunistic index update" done by read-only "diff" and
"status" was about updating cached lstat(2) information in the index for
the next round.  We missed another obvious optimization opportunity: when
there are racily clean entries that will cease to be racily clean by
updating $GIT_INDEX_FILE.  Detect that case and write $GIT_INDEX_FILE out
to give it a newer timestamp.

Noticed by Lasse Makholm by stracing "git status" in a fresh checkout and
counting the number of open(2) calls.

When we had to refresh the index internally before running diff or status,
we opportunistically updated the $GIT_INDEX_FILE so that later invocation
of git can use the lstat(2) we already did in this invocation.

Make them share a helper function to do so.

Some versions of cut do not cope well with lines that do not end in
an LF. In this case, we can completely avoid cut by using the
${var%% *} parameter expansion (suggested by Brandon Casey).

I found this problem when t3404's "avoid unnecessary reset" failed
due to the "rebase -i" not avoiding updating the tested timestamp.

The ancient touch on Solaris 7 thinks that a decimal number supplied as
the first argument specifies a date_time to give to the files specified by
the remaining arguments.  In this case, it fails to parse '1' as a proper
date_time and exits with a failure status.  Workaround this flaw by
rearranging the arguments supplied to touch so that a non-digit appears
first and touch will not be confused.

t7003-filter-branch.sh had a make_commit() function that was identical
to test_commit() in test-lib.sh except that it used tr to create a
lowercase file name from the uppercase branch name instead of
appending ".t".

Not only is this unneeded code duplication, it also was something
simply waiting to fail on case-insensitive file systems.  So replace
all uses of make_commit with test_commit.

Generally, trailing space is removed from the string matched by the
xfuncname patterns.  The exception is when the matched string exceeds the
length of the fixed-size buffer that it will be copied in to.  But, a
string that exceeds the buffer can still contain trailing space in the
portion of the string that will be copied into the buffer.  So, simplify
this code slightly, and just perform the trailing space removal always.

Commit 6106ce46 introduced a test to demonstrate fetch's failure to
retrieve any objects or update FETCH_HEAD when it was supplied a repository
URL and the current branch had a configured merge spec.  This commit
expands the original test based on comments from Junio Hamano.  In addition
to actually verifying that the fetch updates FETCH_HEAD correctly, and does
not update the current branch, two more tests are added to ensure that the
merge configuration is ignored even when the supplied URL matches the URL
of the remote configured for the branch.

On IRIX 6.5, the printf utility in /usr/bin does not appear to handle the

of the string argument and ignore any additional characters in the string.
Work around this flaw by replacing the \000's with 'Q' and using the
q_to_nul helper function provided by test-lib.sh

This problem with printf is not apparent when using the Bash shell since
Bash implements a POSIX compatible printf function internally.
