>Description:
POSIX 2004 describes a utility called fuser(1), which is similar to
fstat(1). Because it would be useless to write an entire fuser(1)
utility that only has a fraction of the functionality of fstat(1), it
would be better to integrate it into fuser(1). 

Two previous attempts were made, none were eventually committed:

 - standards/36076 - suspended, because it was a shell script
 - standards/35682 - not integrated, as it doesn't share any common code
                     with fstat(1).
>How-To-Repeat:
n/a
>Fix:
Apply the following patch:

This utility patches the fstat(1) utility to behave like fuser(1) when
called. It supports all the flags required, including some more (-m, -M
and -N).

The characters printed after the PIDs almost share the same scheme as
the Linux version.
