[PATCH v2 07/22] git-remote-mediawiki: Change style of some regular expressions

["Célestin Matte" <celestin.matte@ensimag.fr>]

- Remove m modifier when useless (m// and // was used randomly; this makes the
code more coherent)
- Remove stringy split (split('c', ...) instead of split(/c/, ...))
- Use {}{} instead of /// when slashes are used inside the regexp so as not to
escape it.
A "split ' '" is turned into a "split / /", which changes its behaviour: the old
method matched a run of whtespaces (/\s*/), while the new one will match a
single whitespace, which is what we want here.
