Thank you.

First, it doesn't seem like it handles attr_reader, attr_writter, 
attr_accessor and method_alias, like I asked at the end of the bug 
report. That line of discussion was somehow dropped.

Second: a minor thing. If I remove the space after '=', 'ABC =4' doesn't 
get recorded.

Third, this is tangential, but I don't think anybody uses the .ruby 
extension for Ruby files (you can see it's not in auto-mode-alist). But 
maybe someone somewhere will use it for something else, and etags will 
erroneously parse that file as Ruby?

On the other hand, you might want to add *.ru, *.rbw, Rakefile and 
Thorfile to the list of Ruby file names.

I'll be sure to let you know if I notice something else.
