Make max6 Python 2/3 agnostic, and make the help usage it prints out more readable

I wish I could find a way to run the exec command without needing a backslash. This works in python 3 but not 2:

e=exec
e(a)

and this works in 2 but not 3:
exec a

If only there were some way to combine them...

Your help message is unreadble, some lines are longer than 6 characters! (notably max6.py).
Also this doesn't actually work for me; I need to call python max6.py in.py out.py

Usage:
max6.py
in.py
out.py

Makes
progs
comply
with
6 char
per
line.

@zbanks This is a problem with your setup. That line is the contents of sys.argv[0], so if you name max6.py something shorter, you won't run into this problem.

@ervanalb: Python 2 / 3 compatible:

exec(a
)
