I've tried to make this happen many years ago, but I never finished
the ZLE widget that did it. The idea was to bind 'tab' to a function
that would replace an occurrence of ~g in $LBUFFER with the output
of rev-parse--show-toplevel and then delegate to normal tab
expansion.

So now I just have

  hash -d g=$(git rev-parse --show-toplevel)

in a pre-prompt function and get the same effect.
