or just my bad memory, or assumption about why something so simple wasn't
implemented (I'm too trusting there was a good reason). all I'm really
sure of is that at present you can't mix degree-only with decimal places
and NSEW in GRASS. Maybe it is a simple libgrass coding fix to enable
it after all. shrug, not relevant for this thread.

but "U" and "f" maybe?

%02d pads the space with a zero. my point was that GRASS expects to
see 123:45E or 123:05E, but 123:5E is considered an error.

you mean in the days before they discovered the number 129? ;-)
