alias_method :qux, :tee, attr_accessor(:bogus)
or
alias_method :qux, :tee, alias_method(:bogus, :bogus2)
are the main options, I suppose. But they might also look misleading,
and indicate that we don't support the paren-using syntax intentionally.
(It's another omission, but AFAICS nobody uses attr_XXX without parens
in the context we're interested in.)

The problem with me updating the tests is I can't revert the
corresponding fix and make sure that the test fails without it.

I believe the file-name rules should be tested in a language-agnostic
way, or just with one language. There's not much point in having all
possible file names in test/etags. Or at least that's how I usually try
to write tests: in as orthogonal way as possible.

You could say so.
It's definitely better than "Exuberant Ctags 5.9~svn20110310" I have
installed through the default Ubuntu repositories.
It's better [0] than "Ctag Revival" [1], at least until they add support
for qualified tags for Ruby [2], which could take a while.
We're probably better in some things, and worse in others, than "Ripper
Tags" [3]. I haven't tried them yet myself.
In any case, it'll give me something to try using day-to-day, when we
have at least some solution for tags being out of date (an experimental
xref backend that simply rescans the whole project every time comes to
mind).
