This adds PCRE v2 support, but as I was adding that I kept noticing other related problems to fix. It's all bundled up into the same series because much of it conflicts because it modifies the same test or other code. Notes on each patch below. Ævar Arnfjörð Bjarmason (12): grep: add ability to disable threading with --threads=0 or grep.threads=0 This really has nothing to do with the rest except I'm using it to test non-multithreaded & threaded PCRE more easily. grep: remove redundant regflags assignment under PCRE Makefile & configure: reword outdated comment about PCRE Just some trivial cleanups. grep: add a test for backreferences in PCRE patterns log: add exhaustive tests for pattern style options & config Yay, more tests! log: add -P as a synonym for --perl-regexp We've had --perl-regexp for years, but not -P like grep, add it. grep & rev-list doc: stop promising libpcre for --perl-regexp grep: make grep.patternType=[pcre|pcre1] a synonym for "perl" test-lib: rename the LIBPCRE prerequisite to PCRE grep: change the internal PCRE macro names to be PCRE1 grep: change the internal PCRE code & header names to be PCRE1 grep: add support for PCRE v2 These combined add the support for PCRE 2. It's split up for ease of readability. The last one's still a bit big, and I could e.g. split up all the Makefile/autoconf stuff into a different patch (which wouldn't do anything without the code), but I thought on balance doing it this way made the most sense.
