This is v2 of a series sent a long time ago, in February 2010. The
patches speed up git grep and pickaxe by using the string search
routines from GNU grep.
Changes since v1:
* Rebased on top of current master.
* obstack.[ch] is now in compat/ (comment by Junio)
* kwset.[ch] is from the latest GNU grep commit which uses GPLv2. The
newer commits uses GPLv3, which is incompatible with GPLv2 used by
Git. There are no significant changes between the two. (pointed out
by Dmitry Potapov and Paolo Bonzini)
* Two new tests for git grep are fixed by this code, see patch 5 for
details.
In v1 Paolo pointed out that the kwset code is never used with more
than one string and therefore a much simpler Boyer-Moore search would
be sufficient (a kwset containing only one string uses a Boyer-Moore
search). However, the Boyer-Moore search implemented in kwset cannot
deal with case-insensitive searches, so the more complicated code is
still there.
