Looking at the old docstrings in notmuch-show.el, I agree they basically
implement Tomi's suggestion.  While I think copying default values of
variables into docstrings creates some minor maintainability traps
(since we then need to remember to look at all the places a variable is
referenced if we change the default value), I'm willing to revert the
patch if people think the tradeoff of better usability is worth it.

It is unfortunate emacs doesn't provide a way to expand the current
value of a variable in the help string, but there we are. It probably
wouldn't be as easy to understand as hand crafted text in any case.
