topic: make revsets like 'foo#stack[0]' work

'stack' relation subscript function is another way to refer to s0, s1, etc. But
instead of aborting in many cases it will simply return an empty set.

#require test-repo

  $ checkflake8() {
  >   if ! (which flake8 > /dev/null); then
  >     echo skipped: missing tool: flake8;
  >     exit 80;
  >   fi;
  > };
  $ checkflake8

run flake8 if it exists; if it doesn't, then just skip
