[issue1553] Escaped characters in http(s) credentials garble hgrc when cloning

[Ferrix Hovi]

New submission from Ferrix Hovi <ferrix at earlypenguin.fi>:

In a rare occasion when there is a character to be escaped in http(s)
credentials, they will contain a percent symbol (%). In my case the letter in my
username is @ which I escape as %40. The clone goes successfully but afterwards
hg gets a brain tumor and dies:

ConfigParser.InterpolationSyntaxError: '%' must be followed by '%'

I wrote an one-line patch that fixes the most acute crash.
