Title: emacs and ctags conflict

Both emacs and ctags install an executable named 'ctags'. Both should let
the user know before trying to install the other one (rather than fail
during linking).

I'm going to write up a longer issue about the larger problem (it's more
complicated than you might think), but this is a fix for the immediate
issue.
