there are 2 ways to save "renaming"
- left the old names (i only describe my methods of naming to let you understand where i am coming from, it was not a suggestion to change existing names in dw)
- use a regular expression correction updater to correct even php codes (this is a tricky, but because $lang[...] is not complex it would be possible. but i would not like to change 3. party codes automatically, and the forum will be maybe full with questions after such a update. i would left old names unchanged, if more skilled and experienced dw coders not see it differently.)
i dont fight for implementations, i only share some ideas. if this is not implemented, i am not sorry for this patch!
a general-text translation project interdependent from dw, to creates a large library would be anyway more useful for such a purpose.
email_signature "-- \n" issue is related to...
https://bugs.dokuwiki.org/index.php?do=details&task_id=2519
...and the only addition...
$lang['email_signature'] = "This mail was send from:\n@DOKUWIKIURL@\n";
...is not part of the universal-text translation idea.
i released this patches to the same time and mix up some arguments. this is a "bug" on me side.
