tweaks: slightly shorten a loop, to place the actual action outside of it

And in the bargain elide a variable, and make it clearer
what the return value is at two early exit points.

[This change makes use of the fact that TRUE (successful write) == 1
and FALSE (failed write) == 0.  But this is already used twenty lines
earlier, for the other call of write_file().]
