Comment(by glynn):

 Replying to [ticket:1491 hamish]:

 > raster.py and vector.py use core.py's parse_key_val() to evaluate the
 results of r.info and v.info, and report the result of `kv[1]` using `=`
 as the field separator.
 >
 > r.info's title, vdatum, and units results, and most of v.info's extended
 metadata results can contain free-from text, which can contain `=` chars.
 And so text containing that will get cut off and only give the result up
 to the first `=`.

 parse_key_val() only splits at the first separator:
 {{{
         kv = line.split(sep, 1)
 }}}
 This results in a two-element tuple, with the first element containing
 everything before the first separator, and the second element containing
 everything after, even if it contains the separator character.

 Unless there are specific cases which either actually don't work or which
 are uncertain based upon the actual behaviour of parse_key_val(), this
 ticket should be closed as "invalid".
