Security checks
---------------
-- `refreshpofiles` uses `system()`, whose args have to be checked more
- thoroughly to prevent any security issue (command injection, etc.).
- > Always pass `system()` a list of parameters to avoid the shell.
- > I've checked in a change fixing that. --[[Joey]]
-- `refreshpofiles` and `refreshpot` create new files; this may need
- some checks, e.g. using `IkiWiki::prep_writefile()`
- > Yes, it would be ideal to call `prep_writefile` on each file
- > that they write, beforehand. This way you'd avoid symlink attacks etc to the
- > generated po/pot files. I haven't done it, but it seems pretty trivial.

- Can any sort of directives be put in po files that will
cause mischief (ie, include other files, run commands, crash gettext,
whatever).
[[bugs/pagetitle_function_does_not_respect_meta_titles]], which might
be fixed by something like [[todo/using_meta_titles_for_parentlinks]].
-### websetup
-
-Which configuration settings are safe enough for websetup, apart of
-`po_master_language` and `po_slave_languages` that already have
-been checked?
-
-> `po_translatable_pages` seems entirely safe. `po_link_to` w/o usedirs
-> causes ikiwiki to error out. If it were changed to fall back to a safe
-> setting in this case rather than error, it would be safe.

### backlinks
`po_link_to = negotiated`: if a given translatable `sourcepage.mdwn`
`po_link_to = current`: seems to work nicely
+### parentlinks
+
+When `usedirs` is disabled and the home page is translatable, the
+parent link to the wiki home page is broken (`/index.html`).
