differently when the command subst is quoted vs not quoted

Re https://www.austingroupbugs.net/view.php?id=1342#c4856

I suspect that's already handled by the (new, I forget which bug it is)
wording that specifies when alias commands take effect.

This is just the same issue as prevents

if [ $SHELL = myshell ]; then
    alias xx=mycommand
    xx foo bar
fi

from working.   Or from defining, and then using, an alias in a function.

Aliases are evil - let's delete them!!!
