[PATCH v4 09/31] git-remote-mediawiki: Change the behaviour of a split

A "split ' '" is turned into a "split / /", which changes its behaviour: the
old method matched a run of whitespaces (/\s*/), while the new one will match a
single whitespace, which is what we want here. Indeed, in other contexts,
changing split(' ') to split(/ /) could potentially be a regression, however,
here, when parsing the output of "rev-list --parents", whose output SHA-1's are
each separated by a single space, splitting on a single space is perfectly
correct.
