Обсуждение: bool abuse in path_encode()

The function path_encode() in geo_ops.c takes an argument "bool closed",
to indicate an open or closed path --- but you can also pass -1 to
indicate "neither".  I propose to change this to an enum to make the
code clearer and less weird.

Egad :-(.

Please change the "default" cases to be "case PATH_NONE", then.
