Can you work around it by putting in your path the 8.3 replacement
names like progra~1?  Yes, it is ugly, I know.

One fix could be to use tab or newline only for word separation.
That would be a rather largish change, however, and not limited
to just that one loop in func_mode_link.  I'm not sure it's worth
it.

Huh?  Does the MinGW sh handle this?  How?

The file searching loop is a very hot one in func_mode_link.  If we
introduce forks there, things can get veeery slow, so we really should
avoid it if we can.
