Fix note markup (#16805).

Patch by Tshepang Lekhonkhobe, reviewed by Georg Brandl.
Make distutils error messages more helpful (#11599).

When running external programs such as a C compiler and getting an
error code, distutils only prints the program name.  With this change,
one can get the full command line by setting the DISTUTILS_DEBUG
environment variable.

This should have no compatibility issues, unless there are tools
that depend on the exact format of distutils debug messages.
