Actually it is a bit more complicated than this. According to the EPSG 
database, Pulkovo_1942 is used in the following countries:
Armenia; Azerbaijan; Belarus; Estonia; Georgia; Kazakhstan; Kyrgyzstan; 
Latvia; Lithuania; Moldova; Russian Federation; Tajikistan; Turkmenistan; 
Ukraine; Uzbekistan.
and Pulkovo_1942_58 is used in the following countries:
Albania; Bulgaria; Czech Republic; Germany (former DDR); Hungary; Poland; 
Romania; Slovakia.

So it seems to me that we should have two separate datum entries in GRASS, 
and that it is arguably a bug treating them both as one.

I would appreciate some suggestions on what the GRASS abbreviation for 
Pulkovo 1942 (58) should be; for Pulkovo 1942 it is S-42 - which IMHO is 
not nice as it has a capital letter in it, but of course we can't change 
it without breaking existing locations.
