Allow wildcards in skip lists

[Arne Jørgensen]

Hi,

On my wish list for GNU Global I have being able to add wildcards in
skips lists.

Emacs' flymake-mode creates temporary copies of files by adding
`_flymake' before the the file extension. I.e. a temporary copy of
`my-code.php' is named `my-code_flymake.php'. So adding `*_flymake.*` to
the skip list will ensured that the file is not indexed by gtags.

I have created a very simple patch that turns `*' in the skip list into
`.*' in the regular expression instead of escaping it.

Kind regards,
Arne Jørgensen
