Description:
MediaWiki (of the latest version?) automatically convert " "(half-width space) to "　"(full-width space) in the input box (including search) and direct URL input and so on.
e.g. http://ja.wikipedia.org/wiki/C%E3%80%80Sharp => http://ja.wikipedia.org/wiki/C_Sharp
This is useful sometimes, but also causes many bugs.

Case 1 "section link in edit summary": (not so critcal)
When there's followng two section:
== foo bar ==
This is half-width section.

== foo　bar ==
This is full-width section.
and input /* foo　bar */ (for full-width section) in edit summary, the link in the summary was auto-converted so it misunderstands that the link target is section "foo bar"(half-width).

Case 2 "user's name": (critical)
If the useaname contains "　"(full-width space), his/her name is also converted automatically in many case. So user contributions page ([[Special:Contributions]]) or other page doesn't work well in this case.
For example, [[User:大野　一将]]@jawiki uses full-width space as the separator between his first and last (you can make sure in his userpage's history [1]). But now his name is auto-converted to [[User:大野 一将]](the separator is half-width), therefore his contributuins can't view ; [[Special:Contributions/大野　一将]] (full-width) [2] is converted to [[Special:Contributions/大野 一将]] (half-width) [3].
Maybe because of the same reason, in his userpage [4] the link to his contributuion in toolbox doesn't show.

And more cases are reported on jawiki's bug report page [[:w:ja:Wikipedia:バグの報告]][5].

I thinks the auto-converting should be disabled while this bug still exists, at least in Japanese.

thanks.
