fmt_compile() does that, but not fmt_scan().

In scan, at least, the caller of fmt_scan() allocates the
buffer but doesn't bother to free it.  So, no, I don't think
it'd be too ugly.

I had noticed that a while ago but wondered if there's
really a need for -width 0.  Though getting rid of fixed
size buffers would be helpful.
