Brian Gernhardt reported that test 'git grep -E -F -G a\\+b' fails on
OS X 10.6.7. This is because I assumed \+ is part of BRE, which isn't
true on all platforms.
The easiest way to make this test pass is to just update expected
output, but that would make the test pointless. Its real purpose is to
check whether 'git grep -E -F -G' is different from 'git grep -E -G -F'.
To check that, let's change pattern to "a+b*c". This should return
different match for -G, -F and -E.
I also made two small tweaks to the tests. First, I added path "ab" to
all calls to future-proof tests. Second, I updated last two tests to
better show that 'git grep -P -E' is different from 'git grep -E -P'.

Add few more tests for "-P/--perl-regexp" option of "git grep".
While at it, add some generic tests for grep.extendedRegexp config option,
for detecting invalid regexep and check if "last one wins" rule works for
selecting regexp type.

This patch makes git-grep die() when -P is used on command line together
with -E/--extended-regexp or -F/--fixed-strings.
This also makes it bail out when grep.extendedRegexp is enabled.
But `git grep -G -P pattern` and `git grep -E -G -P pattern` still work
because -G and -E set opts.regflags during parse_options() and there is
no way to detect `-G` or `-E -G`.

This modest patch adds simple tests for git grep -P/--perl-regexp and
its interoperation with -i and -w.
Tests are only enabled when prerequisite LIBPCRE is defined (it's
automatically set based on USE_LIBPCRE in test-lib.sh).

Add two configration variables grep.extendedRegexp and grep.lineNumbers to
allow the user to skip typing -E and -n on the command line, respectively.
Scripts that are meant to be used by random users and/or in random
repositories now have use -G and/or --no-line-number options as
appropriately to override the settings in the repository or user's
~/.gitconfig settings. Just because the script didn't say "git grep -n" no
longer guarantees that the output from the command will not have line
numbers.

Support the well-know convention of reading standard input instead of a
named file if "-" (dash) is specified. GNU grep does the same.

Breaks in a test assertion's && chain can potentially hide
failures from earlier commands in the chain.
Commands intended to fail should be marked with !, test_must_fail, or
test_might_fail. The examples in this patch do not require that.

* jc/grep-header-all-match-fix:
log --author: take union of multiple "author" requests
grep: move logic to compile header pattern into a separate helper
In the olden days,
log --author=me --committer=him --grep=this --grep=that
used to be turned into:
(OR (HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(PATTERN this)
(PATTERN that))
showing my patches that do not have any "this" nor "that", which was
totally useless.
80235ba ("log --author=me --grep=it" should find intersection, not union,
2010-01-17) improved it greatly to turn the same into:
(ALL-MATCH
(HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(OR (PATTERN this) (PATTERN that)))
That is, "show only patches by me and committed by him, that have either
this or that", which is a lot more natural thing to ask.
We however need to be a bit more clever when the user asks more than one
"author" (or "committer"); because a commit has only one author (and one
committer), they ought to be interpreted as asking for union to be useful.
The current implementation simply added another author/committer pattern
at the same top-level for ALL-MATCH to insist on matching all, finding
nothing.
Turn
log --author=me --author=her \
--committer=him --committer=you \
--grep=this --grep=that
into
(ALL-MATCH
(OR (HEADER-AUTHOR me) (HEADER-AUTHOR her))
(OR (HEADER-COMMITTER him) (HEADER-COMMITTER you))
(OR (PATTERN this) (PATTERN that)))
instead.

test_must_fail will account for segfaults in git, so it should be used
instead of "! git"

This adds an option to open the matching files in the pager, and if the
pager happens to be "less" (or "vi") and there is only one grep pattern,
it also jumps to the first match right away.
The short option was chose as '-O' to avoid clashes with GNU grep's
options (as suggested by Junio).
So, 'git grep -O abc' is a short form for 'less +/abc $(grep -l abc)'
except that it works also with spaces in file names, and it does not
start the pager if there was no matching file.
[jn: rebased and added tests; with error handling fix from Junio
squashed in]
