Thanks for doing this.

What are your thoughts on the preferable approach?

If we strip spaces beforehand then we know that we won't fall foul of any related problems with \fontname; if we patch the NFSS then the approach will be robust for other people's code that also falls foul of the same problem.

Guess we could even do both :)
