Subject: xdiff: use ptrdiff_t for dstart/dend
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f007f4f4b473565fb2e94780028399030926bacb;p=thirdparty%2Fgit.git

xdiff: use ptrdiff_t for dstart/dend

ptrdiff_t is appropriate for dstart and dend because they both describe
positive or negative offsets relative to a pointer.
