Yes, but that won't work for the flags at the beginning and end.
Edge case (hehe) to live with or special cases for those with regexes with
"^${flag} " and "${flag}$"? Even then "^${flag} " won't match if there's
only one flag in there (because of the whitespace), so a full function to
check for existence gets complex to complete.
Thanks,
