Many times I want to refer to 'HEAD^', 'HEAD^^' and sometimes even
further up the tree. It would be really nice if I didn't have to type
'HEAD^' but could only type '^'. Bash completion make things easier
but it automatically inserts a space immediately after HEAD so you
have to hit backspace. I think this change would be good in general
anyway.

Or even '~1', '~3'.

"^" has a problem when used with other things (does "log ^^2
origin" mean "log HEAD^2..origin"?  Or "log HEAD^^2 origin"), so I
do not think it would never fly as an abbreviated syntax.

While I see your "~<N>" much distasteful compared to "^", you still
need to be a bit more careful when analysing the benefit of such an
abbreviation.  To shells used by many people, these mean tilde
expansion ~<N> to refer to elements on the dirstack and you need to
quote, perhaps like \~3.
