This looks reasonable as far as workarounds go. Thanks.

Though maybe a cleaner approach would be not to call 
vc-dir-maybe-narrow-and-show-more-button directly in the 
dir-status-files implementations, but have a new hook which vc-dir would 
set up.

Or a similar separate "output limit" variable which would be honored by 
the backends if set, instead of a hook.
