[GRASS5] Re: [bug #2936] (grass) d.barscale doesn't work (bis)

[Maciek Sieczka]

Hi

I'm affraid my email got lost in all that "whinging" debate so I'm resending
just in case. Please read below. Could that bug be easily fixed? It brings 
troubles to all using EPSG codes in Grass.

Forgive me Hamish, you are right. It should be "unable to open panel file:
No such file or directory" like you say.

My finger had to slip when coping/pasting then.

Yes - but only if creating a new location from EPSG code! And this way I
found the reson that d.barscale doesn't work: the PROJ_INFO file syntax is
different when a location is set up via the Grass interface and when
automatically generated from EPSG code. See this:

Via Grass set up:

unit: meter
units: meters
meters: 1.0

Automatic, from EPSG 2180:

unit: metre
units: metres
meter: 1

After replacing the automatic one with the Grass one d.barscale works fine.

Could there be any more commands which don't like the EPSG-generated
PROJ_INFO files?
