question about intended function of filelib:wildcard/2

[Bjorn Gustavsson]

I have now written the missing test suite and corrected the bug.

I have also corrected the minor bug that 

        filelib:wildcard("/not/a/wildcard/pattern")

would not check that "/not/a/wildcard/pattern" really existed; not it will
check and return an empty list if the file does not exist.

I have also changed the exception that is thrown when the pattern is
invalid, such as in

        filelib:wildcard("{a,")

It used to be exit(missing_delimiter); but is now
erlang:error({badpattern,missing_delimiter}).

The correction will be in included in OTP R10-5.
