I realize that this whole issue isn't very important, but anyway...

I don't understand the reasoning. If my aliases file contains:

alias foo user@domain
alias bar :fail: reason for failure

and I've enabled EXPN, then "EXPN foo" will show "user@domain", but
"EXPN bar" won't show "reason for failure"? Why would anyone
want that behavior?

(But now I'll shut up about this until I care enough to write a patch.)
