Can we force questions that are tagged matplotlib and pylab to have the python syntax-highlighting? Since matplotlib/pylab is a python-only library I don't see why this would be a problem. I've been adding the python tag as a workaround, but this seems like a useless edit. Example:
Most of these already have the python tag, which should suffice. The 340 that don't:
...probably should have it, if they contain actual code. Hint, hint.
That said, there's no harm in enabling the default (auto-detect) formatting for these, since that's what's configured already for python. So I've gone ahead and enabled it.
