(usage): Document the option. * src/mv.c (rm_option_init): Likewise. * src/remove.c (remove_dir): With --one-file-system and --recursive, for each directory command line argument, do not affect a file system different from that of the starting directory.

**************************************
|

This test requires a writable directory on a different
|
|
disk partition, and I couldn't find one. I tried these:
|
|
$CANDIDATE_TMP_DIRS
|
|
Set your environment variable CANDIDATE_TMP_DIRS to make
|
|
this test use a different list.
