hgwebdir: correct name output for path wildcards without prefix (issue2310)

When you pass ´*´ or ´**´ to hgweb, without prefixing it ([paths] / = **),
the first character gets stripped from the resulting names.
To test: findrepos([('/', '**')]) yields ('g-stable', 'hg-stable'), etc.
This patch fixes the issue by special casing the situation where root is ´.´.
