Bug#740275: fuser acts as if -M is specified if any of -acikmsuvw are

[Brad Jorsch]

Package: psmisc
Version: 22.21-1
Severity: important
Tags: patch

Expected output:

 $ src/fuser /tmp/.foo.swp 
 /tmp/.foo.swp:        6073
 $ src/fuser -v /tmp/.foo.swp 
                      USER        PID ACCESS COMMAND
 /tmp/.foo.swp:       me         6073 F.... vi

Actual output:

 $ fuser /tmp/.foo.swp
 /tmp/.foo.swp:        6073
 $ fuser -v /tmp/.foo.swp
 Specified filename /tmp/.foo.swp is not a mountpoint.

The cause seems to be a typo in fuser.c. See attached patch.
