Re: 21.5 Test Suite Failures - regexp tests

On further investigation, it is debatable whether the other failures are errors. (Please ignore the rest of the email if this has been talked to death). The regexps in question all deal with variations of \b on empty or one space strings. For example (match-string "\\b" "") ==> 0 but the test expects nil. If we accept that (string-match "" "") ==> 0, which currently both Emacs and XEmacs agree on, then you could argue that the match is at the start of a empty word. Now my perl is very weak, but I though perl would give an alternative regexp implementation. Please correct me if any of the following is wrong. Perl seems to agree that (string-match "" "") ==> 0 $text = ""; $text =~ // && print "OK\n"; OK But: $text =~ /\b/ && print "OK\n"; is silent. Cheers, Sean
