test-revset: enable for Windows

In MSYS, the test fails like this if the hghave exit at the beginning is
removed:

due to the posix path conversion done by MSYS globally, as explained here

  http://www.mingw.org/wiki/Posix_path_conversion

The solution is a bit lame, but it is simple and works: don't use strings that
look like '/a/b', in order not to trigger the path magic done by MSYS.

So, if we can agree not to insist on testing branch names starting with '/',
then this relatively simple patch makes the test pass both on Windows with MSYS
and Linux.
