Subject: (overwrite_prompt): New function.
X-Git-Tag: TEXTUTILS-2_0_15~433
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=66c2f3a08a7b7ef336db50b04b17c4f3715cd753;p=thirdparty%2Fcoreutils.git

(overwrite_prompt): New function.
(copy_internal): Separate the mv-specific and non-move_mode code
that determines whether to prompt the user.
[move_mode]: Don't make mv fail (i.e. don't return 1) just because
the user declined to remove one or more of the files.
