I read this and was somewhat confused by it.  Could you clarify and
educate me as to your use?  Coreutils is not a "regex package" in the
same way as pcre or slre.  It does use regular expressions such as in
'expr'.  So of course I wondered if you were using a command like
'expr' or were trying to extend coreutils with an additional command.

Also, since the bug-coreutils mailing list is attached to a bug
tracking system every message thread of discussion opens an issue
ticket in the bug tracker.  I believe this issue has been resolved
satisfactorily by the subsequence responses.  Do you agree?

Thanks,
Bob
