[Python-Dev] PEP 263 -- Python Source Code Encoding

[Jeff Epler]

This actually works in vim with "charset plugin":
        let s:pep263='coding[:=]\s*\([-A-Za-z0-9_]\+\)'
        au BufReadPost *.py call ReloadWhenCharsetSet(1, s:pep263)
        au BufReadPost *.py call ReloadWhenCharsetSet(2, s:pep263)
It searches for a RE compatible with PEP263 in the first and second lines.

You could change the pattern from *.py to * if you want to recognize the
emacs-style coding in all files.
