Add some missing markdown quotes.
Add some missing markdown quotes.

I'm usually not a stickler for pedantic markup correctness, but these
two resulted in some legitimately confusing/wrong rendered output in the
HTML on github.

The one in the Android section would cause the prose to be rendered on
the same line after the command which is somewhat annoying.

The on in the Windows section was missing a "close quote" which caused
havok for the rest of the document.
