PATCH: fix assignment of grep-find-use-xargs on Windows/MS-DOS |

On Windows, when find-program points to a GNU-compatible `find'
executable, grep-find-use-xargs is assigned the symbol 'gnu. The
consequence of this is that `rgrep' ends building a command that
contains a pipe: find <args> | xargs -0 grep <args> This ends with
`find' reporting confusing errors about wrong arguments.
An extra test is added to the assigment of grep-find-use-xargs to force
the value 'exec on Windows and MS-DOS.

* progmodes/grep.el: (grep-compute-defaults): always assign
'exec to grep-find-use-xargs on Windows and MS-DOS.
