patchbomb: use single quotes around command hint
Windows command lines use double quotes to quote arguments with spaces.
This change is in a series to unify around using single quotes around
commands, and double quotes around interior arguments.
This changeset is taken on stable for consistency with similar update done
before the freeze.
