REOPENing

This is a request about trimming *all* spaces and underscores before and after a
"/".

Personaly I see more advantages trimming *all* spaces and underscores before and
after a "/" and allow only [[foo/bar]] then having all four variants:
[[foo/bar]], [[foo_/bar]], [[foo/_bar]] and [[foo_/_bar]].

I have no clue how many pages like the three last ones mentioned above exist in
the database already.

best regards reinhardt [[user:gangleri]]

The slash character is primarily a legal, legitimate title character for legal,
legitimate titles. "Subpages" are a cute extra that sometimes appears.

WONTFIX.

Perhaps T48750#2176499 has a better description of the problem.
