There's no need to reparse.  Just make m_string a substring up to m_pathEnd and set m_queryEnd to m_pathEnd.

This is not safe.  We could put non-ASCII characters or control characters like the bell character in the new identifier, and they would need to be percent-encoded.  Just don't touch this function.
As long as you're adding tests, please add a test for this case.

This is unnecessary.

Same thing here.  query might have some characters that need encoding.  Query encoding is more complicated, and it includes more characters and some are dependent on the scheme.
We do actually need to slightly change this function to be more spec-compliant, but that should be a separate patch.  I think the problem was when we set the query to the empty string, just a '?' or two, etc.
