[[plugins/shortcut]] creates link shortcut [[ikiwiki/PreprocessorDirective]]s,
which substitute their argument into the specified shortcut URL to generate
the link target, and use the argument as the link text.  For example, given
the example [[shortcuts]], `\[[wikipedia ikiwiki]]` generates a link to
<http://en.wikipedia.org/wiki/ikiwiki>, with the link text "ikiwiki".  This
works well in many cases; however, for things like the `debbug` example, it
simply uses the number as the link text, which does not always provide
enough context to understand the link at first glance.  For example,
`\[[debbug 397501]]` generates a link to <http://bugs.debian.org/397501>,
with just "397501" as the link text.  While [[plugins/template]] provides a
general solution for arbitrary cases, it would help to have a simple option
via the shortcut plugin to set the link text, with a `%s` substitution.
Thus, something like `\[[shortcut name=debbug
url="http://bugs.debian.org/%s" desc="bug #%s"]]` might suffice on a
Debian-specific wiki to indicate a bug number, while a more general wiki
might use something like `\[[shortcut name=debbug
url="http://bugs.debian.org/%s" desc="Debian bug #%s"]]`.
