Subject: =~ doesn't work with NUL characters
Date: Tue, 13 Jun 2017 11:02:17 +0100	[thread overview]
Message-ID: <20170613100217.GA9529@chaz.gmail.com> (raw)

[[ $'a\0b' =~ 'a$' ]]

returns true both with and without rematchpcre

Same for

[[ abc =~ $'a\0xy' ]]

If not fixable (I'd expect it should be possible at least with
PCRE though, at least for the subject argument if not for the
pattern (where one can use '\0' to match a NUL)), it would be
worth documenting.

The [[ subject = pattern ]] operator seems to be OK in that
regard.
