Here's these two patches.  There's an "if (true)" in 0002 which is a
little weird -- that's there just to avoid reindenting those lines in
0003.

In principle, I would think that these are all backpatchable bugfixes.
Maybe 0002 could pass as not backpatchable since it disallows a command
that works today.  OTOH the feature is rarely used, so maybe a backpatch
is not welcome anyhow.
