When a test fails, it's useful to be able to inspect the output.

Current Perl versions put '.' at the end of the library search path
@INC, although this will be fixed in a future Perl release. This means
that when software loads an optionally-present module, it will be
looked for in the current working directory before giving up. An
attacker could use this to execute arbitrary Perl code from ikiwiki's
current working directory.
Removing '.' from the library search path in Perl is the correct
fix for this vulnerability, but is not trivial to do due to
backwards-compatibility concerns. Mitigate this (even if ikiwiki is run
with a vulnerable Perl version) by explicitly removing '.' from the
search path, and instead looking for ikiwiki's own modules relative
to the absolute path of the executable when run from the source
directory.
In tests that specifically want to use the current working directory,
use "-I".getcwd instead of "-I." so we use its absolute path, which
is immune to the removal of ".".

[[forum/refresh_and_setup]] indicates some confusion between --setup
and -setup. Both work, but it's clearer if we stick to one in
documentation and code.
A 2012 commit to [[plugins/theme]] claims that "-setup" is required
and "--setup" won't work, but I cannot find any evidence in ikiwiki's
source code that this has ever been the case.

The test suite was emitting a lot of ugly gettext warnings;
setting LC_ALL didn't solve the problem for all locale setups
(since ikiwiki remaps it to LANG, and ikiwiki didn't know about
the C locale).
People also seem generally annoyed by the messages when
Locale::Gettext is not installed, and I suspect will be
generally happier if it just silently doesn't localize.
The optimisation came about when I noticed that the gettext
sub was doing rather a lot of work each call just to see
if localisation is needed. We can avoid that work by caching,
and the best thing to cache is a version of the gettext sub
that does exactly the right thing.
This was slightly complicated by the locale setting,
which might need to override the original locale (or lack
thereof) after gettext has been called. So it needs to invalidate
the cache in that case. It used to do it via a global variable,
which I am happy to have also gotten rid of.

See bug #411786. Perl's random corruption of the taint flag is even effecting
the untainting of source filenames now (which AFAICS, is a proper untaint
and always worked before..), and that makes using ikiwiki in perl taint
mode not work at all.

* Plugins can add new directories to the search path with the add_underlay
function.
* Split out smiley underlay files into a separate underlay, so if the plugin
isn't used, the wiki isn't bloated with all those files.
