[PATCH] cwrapper: avoid duplicate strlen calculation.

[Peter Rosin]

Hi!

This is very close to obvious and I very nearly just pushed it out, but
what's the rush?  However, I will push under the 72h rule if noone
speaks up.

It fixes half the issues reported by the clang static analyzer for
my current pet project.

Cheers,
Peter
