No, 'ctags -e' gives pretty much the same output that 'etags' does now. 
So it's definitely acceptable.

I'm not sure.

One direction would be to add `:' to NONAM, so that a method name would 
implicitly match a qualified tag as well. Not sure if it will be a 
problem in some languages (but in, say, Elisp `:' can be a part of an 
identifier).

Another - to make etags-tags-completion-table include both the pattern 
and the explicit tagname in the returned obarray.
