There is a problem here with the -r option in gem_seqno_wrap, as this conflicts
with the --run-subtest option in common_init. This is a general issue with this
method of splitting the responsibility for parsing the command line. As the
common command line options defined in common_init (--run-subtest etc)
do not support short options, a simple solution might be to use some non
printing characters for their getopt return codes, eg
{"list-subtests", 0, 0, '\x0c'}, ....
This way, individual tests are unlikely to clash with these. (I chose '\x0c' since
'l' is the twelfth character ?) I tried this locally and it seemed to work.
