Comment (by knarf):

 QuoteSafe unfortunately does it's job too well. The way simfactory quotes
 is not working in all cases, and it is not in this. For instance, the
 sshcmd is taken into a string which is surrounded by single quotes. If now
 sshsmd is passed to QuoteSafe, it get additional single quotes around it,
 messing up with the overall quoting. Agreed, the quoting in simfactory
 should be improved. E.g. quoting an empty string should result in an empty
 string. But that is another ticket.

 You say the current quoting is off. It works for me. Did you try it and it
 didn't work for you?

 Your concern about multiple trampolines is true: the patch probably does
 not support that. A better quoting should make that possible in a clean
 way. However, are multiple trampolines a real concern for anyone?

 Ok, I agree that we might not want to use the current patch as it is. Do
 we agree that we need a better way to quote command line arguments?
