whereis: reset search mask more carefully
# whereis -m cal -M /usr/share/man/man1/ -f ls
cal: /usr/share/man/man1/cal.1.gz /usr/share/man/man1p/cal.1p.gz
ls: /usr/bin/ls /usr/share/man/man1/ls.1.gz
the -M also resets the search mask, so for 'ls' it returns also
binaries. That's bug. Expected result is:
# ./whereis -m cal -M /usr/share/man/man1/ -f ls
cal: /usr/share/man/man1/cal.1.gz /usr/share/man/man1p/cal.1p.gz
ls: /usr/share/man/man1/ls.1.gz
the search mask has to be sensitive only to -b -m -s options,
otherwise the semantic is pretty messy.
