Joey Hess f2529edcab Fix typo in Danish translation of shortcuts page that caused expoentional regexp blowup.
Complex regular subexpression recursion limit (32766) exceeded at
/home/joey/src/ikiwiki/IkiWiki.pm line 1532.

This doesn't fix the blowup potential itself, it just fixes the typo. :)

A sample page that causes the blowup is attached below for future
reference. The first directive is not terminated. Contributing are the
additional quotes around the following directives, which mean that they can
each be processed as a parameter to the first directive, or as an
individual directive. In resolving this ambiguity, the regexp blows up.
Happily, perl contains the explosion , so I don't think there is an exploit
here.

README.Debian

It's a good idea, and in some cases a requirement, to rebuild your wikis
when upgrading to a new version of ikiwiki. If you have a lot of different
wikis on a system, this can be a pain to do by hand, and it's a good idea
to automate it anyway.

This Debian package of ikiwiki supports rebuilding wikis on upgrade. It
will run ikiwiki-mass-rebuild if necessary when upgraded. The file
/etc/ikiwiki/wikilist lists the setup files of wikis to rebuild, as well
as the user who owns the wiki. Edit this file and add any wikis you
set up.

You can also allow users to maintain their own list of wikis to rebuild,
by listing their usernames in /etc/ikiwiki/wikilist without corresponding
setup files.  ikiwiki will then read their lists of wikis from
.ikiwiki/wikilist in their home directories.


The examples directory contains the source to some example wiki setups.
