FWIW, Removing backslash handling from this function (essentially ignoring
backslashes in command arguments) fixes about 12-15 tests on Windows with
no other changes. I see there's some logic in Args for encoding and
decoding escape sequences, but this only happens if a particular command
option is set, and that command only only appears to be set for the
"prompt" command. I'm not sure if removing the backslash logic from
SetCommandString would interfere with this command in any way, but it
doesn't seem like it would interfere with any other commands, unless I'm
