templatekw: make negrev return empty for wdir() and nullrev
I considered just returning the same output that {rev} returns here,
but {rev} also returns essentially gibberish: either an INT_MAX-kind
of variable for wdir() or -1 for null. Since these are numbers that
are intended to be used for calculations, and since the numbers for
wdir() and -1 are not really very helpful for calculation (and worse,
when used as a revision number -1 is equal to unhidden tip), I figured
the most reasonable thing to do here is to just return nothing for
negrev.
This could potentially break scripts that are expecting to parse a
nonempty integer out of a {negrev}, but that seems like a very remote
concern at this juncture.
