OK, so GUD (in gud-common-init) expands only the first command-line
parameter. So you can fix this by creating a script 'rr-replay' that looks

exec rr replay "$@"

and then run that from GUD and the parameter will expand as expected.

Currently when the first non-global-option argument is not a valid
subcommand we interpret the rest of the arguments as a command to be
recorded. I guess if the first argument is a directory with a `version`
file in it we could treat it as a trace to be replayed (and interpret any
following arguments as replay arguments). That would make replay slightly
more convenient. Worth it?
