hmm, vdatum= and units= are also free-form text
fields and so can not be part of 'eval `r.info -g`'
either. (which must be supported for end-users,
even if shell scripts are not used by the official
release)


also, for core.py's parse_key_val(), if a free-
form string is parsed, and the string contains '=',
then "v = kv[1]" will chop it off prematurely.
(this is a bug in all branches)


probably
 def parse_key_val(s, sep = '=', dflt = None, val_type = None, vsep = None)

needs to have another argument added like
 ..., to_eol = False):

to allow an effect like .split('=')[1:end]
instead of just the kv[1] element.
