regex: use regexec_buf()
The new regexec_buf() function operates on buffers with an explicitly specified length, rather than NUL-terminated strings. We need to use this function whenever the buffer we want to pass to regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated). Note: the original motivation for this patch was to fix a bug where `git diff -G <regex>` would crash. This patch converts more callers, though, some of which allocated to construct NUL-terminated strings, or worse, modified buffers to temporarily insert NULs while calling regexec(3). By converting them to use regexec_buf(), the code has become much cleaner. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
