<p>
Checks if theres a version of <em class="parameter"><code>filename</code></em> which is localized to the current
locale. This is done by appending the full locale name to <em class="parameter"><code>filename</code></em>, separated
by a '.'. If theres no file of that name, it retries using the full locale
name without the encoding (if any), then without the qualifier (if any) and
at last the base locale is tried. If all of those fails, a copy of <em class="parameter"><code>filename</code></em>
is returned.

<p>
The locale is of the general form LANG_COUNTRY.ENCODING @ MODIFIER, where
each of COUNTRY, ENCODING and MODIFIER can be absent.
</p>
<p>
The match is done by actually removing the rightmost element one by one. This
is not entirely according to the freedesktop.org specification, but much easier.
Will probably be fixed in the future.
