address@hidden: cperl-mode problem under emacs 22.1]

[Richard Stallman]

Would someone please try to DTRT, then ack?  Sometimes these problems
are impossible to fix, or impossible without creating worse problems.
But it would be good to try it and see, before giving up.

Subject: cperl-mode problem under emacs 22.1

emacs -q
C-x C-f file.pl
M-x cperl-mode

Type into buffer:

$k =~ s{a}{b};
          ^ the second open brace will fail to insert, generating message:
          Args out of range: 14, 15

This is with the built-in cperl-mode 5.22 in Emacs 22.1.

This does not happen with emacs 21.x or 20.x.

###################################

With cperl-mode 5.23 form ilya, I can type the {}'s, but the following
error is generated instead:

End of `s{ ... }{ ... }' string/RE not found: (scan-error Unbalanced 
parentheses 11 13)

This causes fontification to fail.
