I don't have any problem with 0.31.4-1, but the problem is present with
0.32.1-1 from experimental.  In all cases, i'm upgrading notmuch,
libnotmuch*, and elpa-notmuch in lockstep.

Nothing in NEWS between these versions suggests that my way of binding
keys is now deprecated.

I worry that this is due to one of the two following commits but my
elisp-foo is weak enough that i don't know what the right next steps are:

    emacs: avoid binding unnamed commands in keymaps
    One should never bind unnamed commands in keymaps because doing that
    makes it needlessly hard for users to change these bindings.
    Replace such anonymous bindings with named commands that are generated
    using macros and some boilerplate. Using macros is better than using a
    simple loop because that makes it possible for `find-function' to find
    the definitions. Eat your boilerplate--it forms character.
    Admittedly this approach is quite ugly and it might be better to teach
    the original commands to support different buffers directly instead of
    requiring wrapper commands to do just that.
    Never-the-less as a short-term solution this is better than what we
    had before.

    emacs: don't fset keymaps
    These keymaps are never invoked as commands
    so the function definitions serve no purpose.
