Subject: [PATCH v3 08/10] grep: drop support for \0 in --fixed-strings <pattern>
Date: Mon, 1 Jul 2019 23:20:58 +0200 [thread overview]
Message-ID: <20190701212100.27850-9-avarab@gmail.com> (raw)
In-Reply-To: <20190627233912.7117-1-avarab@gmail.com>
Change "-f <file>" to not support patterns with a NUL-byte in them
under --fixed-strings. We'll now only support these under
"--perl-regexp" with PCRE v2.
A previous change to grep's documentation changed the description of
"-f <file>" to be vague enough as to not promise that this would work.
By dropping support for this we make it a whole lot easier to move
away from the kwset backend, which we'll do in a subsequent change.
