Each time I run xev(1) in an xterm, move the cursor into its window's
upper left black box, perform the M-slash keybinding and hit escape to
exit cwm's prompt; then I move the cursor back into xterm and quit xev
with ^C.
After clean boot with default "us" keymap here M-slash effectively means
`<Alt>/' on my keyboard:
$ xev -event keyboard 2>&1 | tee xev.us.working

Now after switching to german where I type `<Alt><Shift>7' this time as
the slash moved on my keyboard:
$ setxkbmap de

All is working until now; I switch back to english and type `<Alt>/'
again as the first time:

Note that I still pressed escape for consistency even though cwm's
window menu did not even appear.
Reexecuting cwm through "CM-w cwm", i.e. `<Ctrl><Alt>cwm<Enter>' works
in itself and fixes the keymap.
Here's the same xev dance afterwards, no fiddling with setxkbmap or so:
