Seems reasonable I guess. It's really specifying a starting WAL
location, but only to file granularity, so treating the argument as a
file name is sort of a type cheat but seems convenient.
If we do it that way, we'd better validate that the argument is a legal
WAL file name, so as to catch any cases where somebody tries to do it
old-style.
BTW, does pg_resetxlog's logic for setting the default -l value (from
scanning pg_xlog to find the largest existing file name) still work?
