This sort of change to the set of supported syscalls for strace looks
like it should
be in a separate patch to the "move files" patch.

A lot of this (and below) is just coding style fixes. Please make
sure you keep those entirely in their own patches, not mixed
in with functionality changes -- it's much easier to review
that way.
