Subject: zgrep: port to POSIX sed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* zgrep.in (res): When escaping the file name do not rely on GNU
seds extension to POSIX with respect to s/.../\n/. Instead, use
features that should also work with AIX and/or Solaris sed. This is
simpler anyway, and would have prevented the recently-fixed bug.
