df: fix exit code and error messages with --total
When the combination of the file system options with given files or
devices does not lead to output, "df --total" would exit successfully
although it should not.
Examples:
$ df --total --type=xfs / # when / is not an XFS file system
$ df --total --local -t nfs DIR # nfs is remote per se ...
$ df --total -t qwerty /dev/sdb5 # typo in file system type
Furthermore, "df --total" would not print the error message "no file
systems processed" when the file argument does not exist or is otherwise
not accessible.
Example:
$ df --total __not_exist__

df: don't output control characters in a mount point name
It's awkward to read and problematic for scripts when
control characters like '\n' are output.
Note other fields are already handled with mbsalign,
which converts non printable chars to the replacement char.
A caveat to note with that, is the replacement char takes
a place in the field and so possibly truncates the field
if it was the widest field in the records.
Note a more general replacement function, that
handles all printable, or non white space characters,
would require more sophisticated support for various
encodings, and the complexity vs benefit was not
deemed beneficial enough at present.
Perhaps in future a more general replacement function
could be shared between the various utilities.
Note <space> is unaffected in any field,
which could impact scripts processing the output.
However any of the number fields at least could have
spaces considering `LANG=fr_FR df -B\'1`, so it's
probably best to leave spaces, which also allows
scripts to handle mount points with spaces without change.

ls: color each symlink-to-relative-name in / properly
In order for ls --color to color each symlink, it must form the name
of each referent and then stat it to see if the link is dangling, to
a directory, to a file, etc. When the symlink is to a relative name,
ls must concatenate the starting directory name and that relative name.
When, in addition, the starting directory was "/" or "/some-name",
the result was ill-formed, and the subsequent stat would usually fail,
