11 years agosort: simpler fix for sort -u data-loss bug, and for a FMR bug

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.

* src/truncate.c (do_ftruncate, main):
On files where st_size is not portable, fall back on using lseek
with SEEK_END to determine the size.  Although strictly speaking
POSIX says the behavior is implementation-defined, in practice
if lseek returns a nonnegative value it's a reasonable one to
use for the file size.

e.g., GNU/Linux.

Many coding standards, including GNU's, advocate that when
splitting a line near a binary operator, one should put the
operator at the beginning of the continued line, rather than
at the end of the preceding one.  This is for readability:
