Specifically old Win16 programs (identified by the file header) aren't
aware of long filenames. In the case of these old programs, the shell
calls GetShortPathName when replacing %0 or %1, but not when replacing
%L.

For Win32 programs %0, %1, and %L are all the same:

    C:\Temp>ftype Python.File
    Python.File="C:\Windows\py.exe" "%0" "%1" "%L" %*

    C:\Temp>longfilename.py
    sys.argv:
    C:\Temp\longfilename.py
    C:\Temp\longfilename.py
    C:\Temp\longfilename.py

    Short Pathname:
    C:\Temp\LONGFI~1.PY
