Bug fix for strange "E433: No tags file" problem

The plug-in is supposed to automatically register the global tags file
with Vim by setting the "tags" option but this didn't work because of
what's probably a bug in Vim: When you set the "tags" option using the
following syntax, Vim will fail to add the new tags file:

    let &tags = ...

But when you switch to the following syntax it works:

    :set tags=...
