Aliases are only expanded when they are in the position of a command
word, or if they follow an alias whose expansion ends in a space.

\Aliases are only expanded when they are in the position of a command
\word, or if they follow an alias whose expansion ends in a space.

Could you explain why, Brian?  Isn't non-transitivity of aliases very annoying?
