old-http error with .map files

[Satish Balay]

I've recently converted some of our bk repositories to mercurial - but
I'm encountering some difficulties.

Our repository has a file 'bar.map' that is causing 'hg clone old-http://'
to abort with the following error.

However wget on this file works fine - so I'm guessing its a hg issue
with '.map' comsidered something special. This is repoduceable with
the following [and placing the repo in location accessible to a
webserver]

'hg clone ssh:' & 'hg clone http://' [with hg serv] work fine.  This
is with mercurial-0.9

thanks,
Satish
