You want to use PSS('$1') instead of '$1'. Otherwise the backslashes
in front of quotes (added by the /e option) will change the argument
parsing (because the items no longer begin with quotes). Thus
Markup( 'hrule', 'directives', '/\\(:hr (.*?):\\)/e',
It's a PHP misfeature, I don't have any better way to handle it than
putting PSS(...) around things whenever /e is used.

Yes, the backslashes added by /e are the likely culprit.
P.S.: PSS() stands for "PmWiki Strip Slashes". I abbreviated it
because it's used fairly frequently and the longer name would
really clutter up the replacement strings.
