 Yes it works if you type in zone=1-60.

 I'm seeing that +lon_0=-183 again though and I figured out how to
 reproduce it. If you enter "0" or "99" for the zone it automatically
 resets to zone 1 or 60, respectively. Apparently this is only visually. If
 you proceed to the summary page in the location wizard instead of +zone=23
 you will see +proj=tmerc +lon_0=411 etc. ...

 {{{
 -PROJ_INFO-------------------------------------------------

 }}}


 fwiw1: I notice that PROJ_UNITS is uppercased, which seems different to
 how I always seem to have remembered it there.

 fwiw2: I notice this patch no longer has the try: row/column stuff.
 (different things should go into 2 different commits I guess)
