Subject: make urlabs a noop if base url is not provided
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=885bff723998525c10d7ea8ad295547f5fcc939a;p=ikiwiki.git

make urlabs a noop if base url is not provided

This allows urlabs($foo, $config{url}) to be used safely, even if
no url is configured.
