In MH-E code that had been working in GNU Emacs for years, an XEmacs user reported an infinite loop stemming from the following call: (replace-in-string "foo" "/*$" "/") The regexp ensures that there is one, and only one, trailing slash. Works in Perl, vi, GNU Emacs. That it doesn't in XEmacs is a bug. And a nasty one at that--I don't think replace-in-string should ever let a lowly regexp put it into a loop. GNU Emacs: M-: (replace-regexp-in-string "/*$" "/" "foo") --> foo/ vi: echo foo | vi -: :s/\/*$/\//g --> foo/ Perl: echo foo | perl -p -e 's|/*$|/|' --> foo/ -- Bill Wohler <wohler(a)newt.com&gt; http://www.newt.com/wohler/ GnuPG ID:610BD9AD Maintainer of comp.mail.mh FAQ and MH-E.
