I'd like the ability to use a shortcut, but declare an explicit link text
rather than using the link text defined on [[/shortcuts]].  For example, if I
create a shortcut `protogit` pointing to files in the xcb/proto.git gitweb
repository, I don't always want to use the path to the file as the link text;
I would like to src/xcb.xsd, but use the link text "XML Schema for the X
Window System protocol".  --[[JoshTriplett]]

One possible alternative, would be a general `\[[!url ]]` scheme for all kinds of links. As mentioned in [[Short_wikilinks]], I have wanted a way to enter links to the wiki with markdown-style references,
specifying the actual target elsewhere from the text, with just a short reference in the text. To facilitate automatic conversion from earlier (already markdownised) "blog", I finally ended up writing a custom plugin that simply gets the location of wikipage, and use markdown mechanisms:

    Here [is][1] a link.

      [1]: [[!l a_page_in_the_wiki]]

    Obviously [this]([[!l another_page]]) also works, although the syntax is quite cumbersome.

So that the 'l' plugin inserts the location the page there, and markdown does the rest. My plugin currently fails if it can't find the page, as that is sufficient for my needs. Differing colouring for non-existing pages is not doable in a straightforward manner with this approach.

For external links, that is no concern, however. So you could define for each shortcut an alternative directive, that inserts the URL. Perhaps `\[[!url shortcutname params]]` or `\[[@shortcutname params]]` (if the preprocessor supported the @), and this could be extended to local links in an obvious manner: `\[[!url page]]` or `\[[@page]]`. Now, if you could just get rid off the parantheses for markdown, for the short inline links --[[tuomov]] (who'd really rather not have two separate linking mechanisms: ikiwiki's heavy syntax and markdown's lighter one).

I've added code to make the \[[!foo 123]] syntax accept a _desc_
parameter. I've named it like this to signal that it overrides the
_desc_ provided at description time. `%s` is expanded here as well.
