How about
Patterns should not include the separator (unless escaped), even
as part of a character class. In conformance with Posix, the Cray
`sed' rejects `s/[^/]*$//': use `s,[^/]*$,,'. Even escaped,
I'd rather recommend 's|[^/]*$||' instead, consistent with the rest of our
recommendations to prefer | over non-shell-metacharacters.
We should change that recommendation, since escaping | with \| is not
portable, while for example :, # or % are portable in practice (I know
of no regex engine where anyof \[:#%] is special).
Suggesting the comma however is definitely a bad idea.
I guess you were trying to point out that GNU sed 3.02 is what is
currently in use on MinGW? That wording came across a bit awkwardly; how
about:
For example, MinGW ships with GNU sed 3.02, which rejects `s,x\{1\,\},,'.
Agreed.
