I think we need more than one synopsis line.  Maybe

Usage: pg_xlogdump [OPTION] --path=PATH --start=STARTPOS pg_xlogdump [OPTION] [STARTSEG [ENDSEG]]

And then, under "options", do not list --path and --start (because
that'd imply they can be used when STARTSEG is specified, which I
understand they cannot).

Do we have any other possible operation mode?  IIRC those are the only
two possible modes.
