RepOrigin vs. replorigin

Hi all,

While reading the code in origin.c, I found the inconsistent use of
RepOrigin and replorigin (with an 'l') quite confusing -- especially
when trying to determine names for new functions or variables. For
instance,

- RepOriginId
- InvalidRepOriginId

- RM_REPLORIGIN_ID
- XLOG_REPLORIGIN_{SET|DROP}
- replorigin_session_origin
- replorigin_session_xxx() functions

Is there a conventional rule for choosing one over the other depending
on context? Or should we consider unifying these naming conventions?"

Regards,
