 Security checks

-- `refreshpofiles` uses `system()`, whose args have to be checked more
-  thoroughly to prevent any security issue (command injection, etc.).
-- `refreshpofiles` and `refreshpot` create new files; this may need
-  some checks, e.g. using `IkiWiki::prep_writefile()`
+- Can any sort of directives be put in po files that will
+  cause mischief (ie, include other files, run commands, crash gettext,

-- fix the duplicated PO header mysterious bug
-- fix the "duplicate message definition" error when updating a PO
-  file; do PO files need normalizing? (may be a side effect of
-  previous bug)

 - fix infinite loop when synchronizing two ikiwiki (when checkouts
   live in different directories): say bla.fr.po has been updated in
   repo2; pulling repo2 from repo1 seems to trigger a PO update, that
   changes bla.fr.po in repo1; then pushing repo1 to repo2 triggers

+does. This is actually a duplicate for
+[[bugs/pagetitle_function_does_not_respect_meta_titles]], which might

+`po_link_to = negotiated`: if a given translatable `sourcepage.mdwn`
+links to \[[destpage]], `sourcepage.LL.po` also link to \[[destpage]],
+and the latter has the master page *and* all its translations listed
+in the backlinks.

 
 

-### websetup
+`po_link_to = current`: seems to work nicely

 
 

-Which configuration settings are safe enough for websetup?
+### parentlinks
+
+When `usedirs` is disabled and the home page is translatable, the

-Translating online

-**FIXME** preview does not work for PO files.

-A message-by-message interface could also be implemented at some

-
-Translating offline without VCS access
---------------------------------------
-
-The following workflow should be made possible for translators without
-VCS access who need to edit the PO files in another editor than a web
-browser:
-
-- download the page's PO file
-- use any PO editor to update the translation
-- upload the updated PO file
-
-Implementation note: a generic mechanism to upload a page's source is
-needed: it's only an alternative way to allow saving a the modified
-page's source with the CGI.
-
-### Short-term workflow
-
-A possible workaround is:
-
-- pretend to edit the PO file online
-- copy the PO file content from the textarea
-- cancel the edit
-- paste the content into a local file.
-- edit the local file in any PO editor
-- pretend to edit the PO file online
-- paste the modified local file's content into the edit textarea
-- save
