You're seriously suggesting that:

-   ===  ===================================================
-   '.'  acquired while irqs disabled and not in irq context
-   '-'  acquired in irq context
-   '+'  acquired with irqs enabled
-   '?'  acquired in irq context with irqs enabled.
-   ===  ===================================================
+   =====  ===================================================
+   ``.``  acquired while irqs disabled and not in irq context
+   ``-``  acquired in irq context
+   ``+``  acquired with irqs enabled
+   ``?``  acquired in irq context with irqs enabled.
+   =====  ===================================================

this change makes the lockdep docs less readable?

It's not the markup that makes the lockdep documentation hard to
understand.
