I'm quite happy with '.hgrc', just not happy with reading this 
ancestor directories being default behaviour. Moving to 'hgrc' 
instead will introduce additional issues with backuped .hg/hgrc 
and global configuration files.

Actually, I think most flexible way to solve original problem is 
to add option like:

hgrc = ../.hgrc

into ~/.hgrc, instructing hg to read configuration file relative 
to repo root (or relative to .hg directory, keeping in mind the 
default '.hg/hgrc'). With this we basically get:

1. User knows about what will happen, so no POLA violation.
2. Only some known places should be examined when debugging 
configuration, no tree traversal by hand.
