[issue1417] "maximum recursion depth exceeded " exception when cloning to fncache layout on windows

[vincentcr]

New submission from vincentcr <vincentcr at netmosphere.net>:

Using mercurial 1.1+20081203 on Windows, when trying to clone --pull with
fncache enabled, I get the exception stacktraced below, which looks to me like
an infinite recursion. 

Previously that repo was affected by issue 839 ("Hg local store creates paths
too long for Windows"). this was an attempt to use fncache to solve that issue.
The same operation succeeds on linux.

The same error occurs whether I try to clone a local repo created with
usestore=0, or a remote repo hosted on linux created with usestore=1.
