Subject: (enum backuptype): Rename none -> no_backups,
X-Git-Tag: v5.3.0~693
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e6bcd96876db4fe6670a2b82e8d28af92f8e3acb;p=thirdparty%2Fcoreutils.git

(enum backuptype): Rename none -> no_backups,
simple -> simple_backups, numbered_existing ->
numbered_existing_backups, numbered -> numbered_backups
to avoid shadowing problems.  All uses changed.
(VALID_BACKUP_TYPE): Don't evaluate arg more than once.
