[Bug 597623] [NEW] Meaningless error message when option -e is used without argument

[Jean-Baptiste Lallement]

Public bug reported:

Binary package hint: chkrootkit

When -e is used without argument the error message doesn't tell much about the error:
$ chkrootkit -e
shift: 2659: can't shift that many

It should display the help of chkrootkit.

Additionally, the documentation of the -e option could be improved by explicitly showing that arguments are required:
-e files/dirs       
    Exclude known false positive files/dirs, quoted, space separated.
instead of
-e     Exclude known false positive files/dirs, quoted, space separated.
