Suggest a simpler mechanism than regexes, to avoid the potential exploits caused by exposing regexes to web edits. Rename proposed debchangelog shortcut to debcl.

+Fair enough.  I only proposed regexes for the purposes of generality.
+
+That said, some simple text substitution mechanisms might handle many of these
+cases without the need for a specialized plugin beyond [[plugins/shortcut]].
+For instance, substring extraction would suffice for the `debcl` shortcut, and
+something like a split function would work for the `mmlist` shortcut.
