brilliant, i'd hope this, or something similar to this, can
get moved into the python source. the one thing it is still
missing is the problem with

#!/usr/bin/env python

and line endings, but that is more a shell problem than a
python problem. still there may be some way to "fool" the
shell/python interaction to ignore any incorrect linefeeds,
like some sort of "ignore" flag that would eat the linefeed

#!/usr/bin/env python -eat

that would definitely run on unix with windows linefeeds. i
don't know if it would fly on unix with mac linefeeds though?
