* Noteworthy changes in release 3.2 (2018-12-20) [stable]
** Changes in behavior
The --files-without-match (-L) option now causes grep to succeed
when a file is listed, instead of when a line is selected. This
resembles what git-grep does.
** Bug fixes
The --recursive (-r) option no longer fails on MS-Windows.
[bug introduced in grep 2.11]
** Improvements
An over-30x performance improvement when many 'or'd expressions
share a common prefix, thanks to improvements in gnulib's dfa.c,
by Norihiro Tanaka. See gnulib commits v0.1-2110-ge648401be,
v0.1-2111-g4299106ce, v0.1-2117-g617a60974
An additional 3-23% speed-up when searching large files, via
increased initial buffer size.
grep now diagnoses stack overflow. Before grep-2.6, the included
regexp code would detect it. Since 2.6, grep defaulted to using
glibc's regexp, which lost that capability.
