The idea can be to keep unrelated ignores separately. For instance 
emacs.hgignore could filter all
those *~, .#* etc files, winbuild.hgignore could filter .obj and .exe, 
etc. The same concept which one can
see (for instance) heavily used in debian /etc.

Hmm, not truly related idea, but maybe mercurial could even distribute 
some such ready to use files.
Then, instead of having everybody re-invent correct regexps, one could say
       include /etc/mercurial/emacs.hgignore
in localignore and be happy....
