So, in view of these arguments and those put forward by Pavel
downthread, I think the attached is an acceptable patch for the master
branch.  It doesn't apply to back branches though; 9.4 and 9.3 have a
conflict in tab-complete.c, 9.2 has additional conflicts in command.c,
and 9.1 and 9.0 are problematic all over because they don't have
src/common.  Could you please submit patches adapted for each group of
branches?
