Now Hasktags generates Emacs etags format "TAGS" files as well as ctags format "tags" files.

It can thus be used with a wider range of editors than previously.
	(specifically Emacs/XEmacs)

I don't think this change should affect anything other than hasktags itself, and it makes hasktags a lot more useful (given how many people use Emacs), so it might be good to merge this into STABLE.
