avoid interpretation of special characters

[Eric Smith <es@xxxxxxxxxxxx>]

For my command (say mut), I want to avoid shell interpretation of
characters like ~ and > or <
so when I go mut  ~f foo and ~r <2w ~r >1w
I want those characters passed literally to the script.
(instead of obviously have to use backslash or quotes for this
purpose.

Thanks!
