Add feature to WMD for re-aligning code blocks
People seem to be prone to just paste code from their IDE into stackoverflow, often with reams of whitespace on the left-hand side. This unnecessarily wastes space and often also cuts lines on the right side.
Repairing that manually is almost as annoying as the breakage itself.
Proposal: after detecting a code-block, remove
(smallest number of leading spaces) - 4 spaces from every line.
