That makes more sense, though as before this would normally not trigger 
loading of the file, since the .hgrc would be owned by someone else.

If this seems like a real issue to people, the files in ancestor 
directories could instead be called 'hgrc' (no dot), which would prevent 
possible conflicts with ~user/.hgrc, and ensure that ls (without -a) 
would make such files immediately visible. In such a case it would just 
be necessary to specifically exclude any **/.hg/hgrc - as could happen 
with repositories nested inside another repository's .hg directory, for 
example versioned MQ storage.
