I've done this part, with the projection's full name between the
abbreviated name and the parameter descriptions, so the format is now
e.g.:

	AEA:Albers Equal Area:LAT0=ask,23.0;LAT1=ask,29.5;LAT2=ask,45.5;LON0=ask,-96.0;X0=ask,0.0;Y0=ask,0.0

Done.

As for why it wasn't noticed, that's probably because most people just
press Enter to use the default (meter/meters), which skips the use of
that table.

BTW, I'm wondering whether the following entries should be kept:

	nanometers:nanometer:1.000000e-09
	microns:micron:1.000000e-06
	angstroms:angstrom:1.000000e-10
	decinanometers:decinanometer:1.000000e-10
	lightyears:lightyear:9.460530e+15

I presume that these were included as a joke, given that microns are
included yet millimetres are omitted.
