The only documentation is in the file itself and describes a Python
wrapper around the C function defined here, but digging though the git
history this Python wrapper doesn't seem to have ever actually been
generated by SWIG.
This file was also marked as deprecated in 2005.
Fixes#2390Fixes#2391
Remove duplicate (aside from comment formatting) embed15.i.
Remove references to Python 1.5.
Tested and remarkably still works with Python 2.7, so update
documentation and comments to reflect that.
