Ideally they should be left untracked not ignored.

While devs can certainly add them to the .hgignore list to make life 
easier, a repository should be clean of extra files (or shown as 
untracked).

I'd add that generated files (like the one generated from pgen) 
shouldn't be part of defaul make target but keept as fully tracked files 
(and regenerated on demand through a special make target).

I hope this helps.
