Subject: hooks: allow callers to capture output
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=45d2d974d02033790ad552adf2b46a40375c34aa;p=thirdparty%2Fgit.git

hooks: allow callers to capture output

Some server-side hooks will require capturing output to send over
sideband instead of printing directly to stderr. Expose that capability.
