docs: --ignore=regexp or --ignore=glob ?

Hi,

I'd like to report a documentation bug.

In current master (revision 655e8e4a3d9a), the manual says:

> @item --ignore=@var{regexp}
> This (repeatable) option lets you suppress acting on files that match the
> given perl regular expression.  For example, using the options
> 
> @example
> --ignore='*.orig' --ignore='*.dist'
> @end example

The argument is described as a regexp in the synopsis and in the prose,
but the example, '*.orig', is not a valid regular expression; it's a
glob pattern.

Cheers,

Daniel
