#     exec: load_script: Do not exec truncated interpreter path
#     
#     Commit 8099b047ecc4 ("exec: load_script: don't blindly truncate
#     shebang string") was trying to protect against a confused exec of a
#     truncated interpreter path. However, it was overeager and also refused
#     to truncate arguments as well, which broke userspace, and it was
#     reverted. This attempts the protection again, but allows arguments to
#     remain truncated. In an effort to improve readability, helper functions
#     and comments have been added.
