Subject: po: factorize extraction of a slave page's masterpage and lang
X-Git-Url: https://sipb.mit.edu/gitweb.cgi/ikiwiki.git/commitdiff_plain/c5513548c9d43923829c9bc2080a3e1bb9e2cac0

po: factorize extraction of a slave page's masterpage and lang

The very same code was repeated at dozens of places.

NB: the real work is now done is _istranslation(), which is memoized,
so the additional function calls overhead should be compensated.
