Comment (by glynn):
Replying to [comment:7 martinl]:
> seems to be problem with _spawnl
Yep. _spawnl() simply concatenates its arguments, with spaces between
them; it doesn't perform any quoting.
An example of "correct" quoting can be found in escape_arg() in
lib/gis/spawn.c. "correct" in quotes because it's up to the C runtime as
to how to parse the command line into individual arguments; the
escape_arg() function matches the MSVC behaviour, and is the same
algorithm as used by e.g. Python's subprocess module (see list2cmdline()
in subprocess.py).
