Subject: grep: show --debug output only once
X-Git-Tag: v1.7.12.2~2^2~9
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=208f5aa42615671bae1e55de20a58d9ba046d3e8;p=thirdparty%2Fgit.git

grep: show --debug output only once

When threaded grep is in effect, the patterns are duplicated and
recompiled for each thread. Avoid "--debug" output during the
recompilation so that the output is given once instead of "1+nthreads"
times.
