Subject: commit: be more precise when searching for headers
X-Git-Tag: v2.12.2~13^2~1
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/50a01cc48c9a46fe75e4a014fb7847c2f4482406?ds=inline;hp=--cc

commit: be more precise when searching for headers

Search for a space character only within the current line in
read_commit_extra_header_lines() instead of searching in the whole
buffer (and possibly beyond, if it's not NUL-terminated) and then
discarding any results after the end of the current line.
