Set new multivar values using unmatcheable regexp.

Seems that regexp in Mac OS X and Linux were behaving
differently: while in OS X the empty string didn't
match any value, in Linux it was matching all of them,
so the the second fetch refspec was overwritting the
first one, instead of creating a new one.

Using an unmatcheable regular expression solves the
problem (and seems to be portable).
