I note in passing that '/usr/bin/env python' is hard-coded in the launcher, which conforms to the above documentation.

A single character (space or tab) is also hard-coded in Emacs's python-mode.

But there is no hard requirement in Unix, if I correctly understand it, that '/usr/bin/env' be separated from 'python' (or whatever) by exactly one space.

No, there is no hard requirement; the shebang still is not standardized AFAIK. A single space is probably the most portable choice, however.

It would not be hard to allow arbitrary whitespace, but I think documenting the restriction is sufficient.
