[PATCH] remote-hg: unquote C-style paths when exporting

[Antoine Pelisse <apelisse@gmail.com>]

git-fast-import documentation says that paths can be C-style quoted.
Unfortunately, the current remote-hg helper doesn't unquote quoted
path and pass them as-is to Mercurial when the commit is created.

This result in the following situation:

- clone a mercurial repository with git
- Add a file with space: `mkdir dir/foo\ bar`
- Commit that new file, and push the change to mercurial
- The mercurial repository as now a new directory named '"dir', which
contains a file named 'foo bar"'

Use python ast.literal_eval to unquote the string if it starts with ".
It has been tested with quotes, spaces, and utf-8 encoded file-names.
