why am I asked to Visit tags table for ~/.emacs.d/init.el?

[Sam Halliday]

Hi all,

I have a separate tags table for each project/directory that I'm working with, 
which is ideal. When I find-tag in any of my projects for the first time since 
starting emacs, the correct tags table is automatically discovered and 
selected, which is great.

However, if I do find-tags in my ~/.emacs.d/init.el I still get asked which 
tags table to use, despite the fact that there is a TAGS file in ~/.emacs.d

Is this expected behaviour? I would have thought that the TAGS file would be 
trivially discovered.

Best regards,
Sam
