bug#6674: PATCH: fix assignment of grep-find-use-xargs on Windows/MS-DOS


From: Óscar Fuentes
Subject: bug#6674: PATCH: fix assignment of grep-find-use-xargs on Windows/MS-DOS
Date: Tue, 20 Jul 2010 05:49:35 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux)

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.
