Fix allocations at the start of split_into_argv.

Browse Source 
While doing that parametrisation I noticed three strlen calls that
could obviously be replaced with one - and then I also noticed that
there were missing parens in an expression that should have
been (n+1)/2, making it n + 1/2, i.e. just n, due to integer
arithmetic.

Happily that bug meant we were _over_-allocating rather than under,
but even so, how embarrassing. Fixed.
