[COMMIT] Accept "\r\n" line-endings on all hosts

[Mark Kettenis <kettenis@gnu.org>]

In the discussion about elimination of the Cygwin and DJGPP xm.h files
we seemed to have reached agreement on this.  Actually this is a real
improvement, since it will allow you to execute scripts copied from a
system using the MS-DOS convention without converting them.

Tested on i386-unknown-freebsd4.7.
