I understand what you mean in the context of this thread, but I think
the two uses of the term 'command' might be confusing to someone who
opens the file in a year or three.  How about:

# Precommands which allow their wrapped command to be a builtin.
# All of these are necessarily builtins or reserved words themselves, but not all builtin precommands are listed here: for one, the 'command' builtin is excluded.
