Done, though I wrapped the char** in a new charstring_t type.
It keeps track of the character count, accounting for multibyte
characters.

Ken, I removed -bufsize from fmttest because it no longer did
anything.

I don't think we ever resolved how to handle this:  wcwidth()
returns -1 for the width of newlines, and other non-printable
characters.  And the profile setting idea didn't fly.  And I
don't know if it's worth adding another switch just to not count
the newline.
