I noticed tonight when Jeronimo was moving a bunch of pages from the
article namespace into Wikipedia: namespace that the talk pages weren't
being automatically moved over to Wikipedia talk:, even though he had
been using the check box to automatically move the talk page. (They can
be moved manually, but that defeats the purpose of the checkbox!)
Looking at SpecialMovePage.php I see the comments:
# Move talk page if (1) the checkbox says to, (2) the source
# and target namespaces are identical, (3) the namespaces are not
# themselves talk namespaces, and of course (4) it exists.
which conditions are dutifully followed by the code; number two is the
one that's catching us here.
If there's a good reason behind that, it needs to be documented. If not,
it ought to be changed to handle moving talk pages across namespaces (so
long as neither the source nor destination namespace of the main article
is a talk namespace) to accord with current user expectation.
