"direct recursion check for aliases"?  I am not sure what you mean
by that, but anyway.

If I recall correctly, it is intended that we disallow run_argv()
doing handle_alias() twice (or more).  But the ultimate objective is
to forbid infinite loops, "git foo" expanding to "git bar" which in
turn expanding back to "git foo", and the current "do not expand
alias to another" is a simple but too strict implementation.  As
long as a replacement implementation still forbids infinite loops
with reasonable cost and complexity, I do not think we would mind
such an improvement to allow alias expanding to another alias.
