New description:
[http://www.python.org/dev/peps/pep-0263/ PEP 263] says that the encoding
line for a Python file should match a certain regular expression in the
first or second line, but the preparser seems to be looking for the
precise string "# -*- coding: utf-8 -*-".
We should follow PEP 263 precisely. In particular, this will make it easy
for SageTeX users to specify an encoding; because of TeX weirdness that I
don't entirely understand, it is easiest to write the line "## -*- coding:
utf-8 -*-" to the generated script.
* Apply `trac_10440.patch` to the sage library repository.
* Apply `trac_10440_scripts_repo.patch` to the sage scripts repository.
