Proposal for issue #132 (superseding pull request #33)

Hey.

Thanks for one of the best vim plugins there is :-)

I came across issue #132 and used the suggested code a a prototype for patching your plugin appropiately. 

There's already a pull request waiting (#33), but it does not allow for user configuration of the behavior. This patch will not change the default behavior of vim-easytags.

Regards,
Kim
