Notes:
v8, v9:
no changes
v7:
Use OPT_BOOL instead of OPT_BIT.
This allows for --no-atomic option on the command line.
v6:
- OPT_BIT(0, "atomic", &flags, N_("use an atomic transaction remote"),
+ OPT_BIT(0, "atomic", &flags, N_("request atomic transaction on remote side"),
skipped v4 v5
v2->v3:
* s/atomic-push/atomic/
* s/the an/an/
* no serverside, but just remote instead
* TRANSPORT_PUSH_ATOMIC instead of TRANSPORT_ATOMIC_PUSH
Changes v1 -> v2
It's --atomic now! (dropping the -push)
