I think the idea was to have legible dumps (i.e. avoid hashing everything) but
also to fit them into the various  name[GFC_MAX_SYMBOL_LEN]  variables which
simply do not take longer names.

If you think one can/should improve the scheme, feel free to propose something
better. (Only) when switching to the new descriptor, we can change it.
