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.

A better fix, just check that what $) returns is what it was asked to set,
and ignore $! entirely.

This fixes a problem sgran saw on alioth. Apparently nss-db sets errno to
ENOENT as a side effect trying to read an optional file, but succeeds
anyway. Then, somehow, errno remains set across the library calls made by
$).
So unset it first as a workaround; there's probably a nss-db, libc, and/or
perl bug underneath.

to be created owned by some group other than the default. Useful
then there's a shared repository with access controlled by a group,
to let ikiwiki run setgid to that group.
