Yes, it is wrong.  But this is what turns up when you google for a way to
get the keybindings to work. The original code only works when you use the
emacs customize interface. Many people don't use customize, either by choice
or ignorance, and attempt to set things up in .emacs. The docs didn't make
this situation clear so I spent some time trying to get to keybindings setup
with little success.  I actually spent more time googling for a solution
than I did reading the code and generating the patch.

No real merit I can think of, but it does provide a method to allow you to
establish keybindings even after you have entered gtags-mode.

Not that I'm aware of. Gtags-bind-custom-keys could easily be an internal
routine or simply unadvertised; any public benefit is at best trivial.
