As I intended to discuss the rational behind the code and find a more
correct solution I thought the developer list would fit...

I can't make a suggestion like this as long as I don't know what
the intention of setting HGRCPATH='' was in the first place.  As stated
above the comment is misleading as hgrc is not used for any kind of
localization (I wrote "to my best knowledge" but I double checked with
an core Mercurial developer in the meantime).

So at the moment it looks as if the HGRCPATH='' can be simply removed!

But there might be some other reasons (Bug#5846 seems to indicate that)
besides the localization issue for trying to deactivate .hgrc files...

Maybe Chong Yidong knows some details, as he made the last changes to
the code in question?
