You've exceeded 32 characters!  Perhaps you could change:

            return basename[:30]+"$"+tail

to:

            return basename[:21]+"$"+tail

But then you'd get something like this for your long identifier:

    group1_group2_group3_$AyQVQUXoyf

which seems to miss out on a crucial bit: namely the field name.

Also it's hard to imagine a way to keep things readable when we don't
know what the original identifiers look like :)
