Bug in GNU find version 4.1

[Adam S. Moskowitz]

GNU find version 4.1 has a bug in handling directory names that start
with the characters tilde (~) or or bang (!). To wit:

        $ ls
        !foo ,foo foo

        $ gfind --version
        GNU find version 4.1

        $ gfind foo -print
        foo

        $ gfind ',foo' -print
        gfind: invalid predicate `,foo'

        $ gfind '!foo' -print
        gfind: invalid predicate `!foo'

Please don't tell me "just use ./,foo"; other (non-GNU) versions of find
have no problems with this.

FWIW, I have tested this on IRIX 6.2 and (RedHat) Linux 6.2.
