There are no platform standard rules to follow when splitting a path
list. A string split() on os.pathsep suffices. If you don't have a
special use for empty entries, you can filter the result with a list
comprehension, e.g. [p for p in (os.environ.get('MYPATH') or
default).split(os.pathsep) if p]. The `default` value here is for when
MYPATH isn't defined or has an empty-string value.
