test-lint: only use only sed [-n] [-e command] [-f command_file]
From `man sed` (on a Mac OS X box):
The -E, -a and -i options are non-standard FreeBSD extensions and may not be available
on other operating systems.
From `man sed` on a Linux box:
REGULAR EXPRESSIONS
POSIX.2 BREs should be supported, but they aren't completely because of
performance problems. The \n sequence in a regular expression matches the newline
character, and similarly for \a, \t, and other sequences.
The -E option switches to using extended regular expressions instead; the -E option
has been supported for years by GNU sed, and is now included in POSIX.
Well, there are still a lot of systems out there, which don't support it.
Beside that, IEEE Std 1003.1TM-2017, see
http://pubs.opengroup.org/onlinepubs/9699919799/
does not mention -E either.
To be on the safe side, don't allow -E (or -r, which is GNU).
Change check-non-portable-shell.pl to only accept the portable options:
sed [-n] [-e command] [-f command_file]
