Subject: When adding a name to the table of macros and environments, make sure it
X-Git-Tag: v2.3c1~6068
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3c1ff5c766191389a05153370f5217c1b71bdc08;p=thirdparty%2FPython%2Fcpython.git

When adding a name to the table of macros and environments, make sure it
is not already present.  If it is, raise an exception, since that should not
happen in a well-defined conversion.
