Invalid error for jsmath and pngmath when both are deselected
When running sphinx-quickstart, I press enter for these questions.
pngmath: include math, rendered as PNG images (y/N) [n]:
jsmath: include math, rendered in the browser by JSMath (y/N) [n]:
This should choose 'n' for both (since its the default). However, I then get the error message:
"Note: pngmath and jsmath cannot be enabled at the same time. pngmath has been deselected."
Neither is actually selected.
