If the page contains/combines many different ways of doing things,
this creates confusion, especially if the distictions are not explained.
And it would be unnecessary to explain the HEAD^ and HEAD~1 similarities
in every page where these two get mixed.

PRICPLES:

1. The novice user is best served by making things simple and uniform.

2. Utilize concepts that may already be familar. E.g. other VCS/SCM tools
   have concept of counting back revisions with negative numbers: -1,
   -2, -3; so following this same idea in git manual pages would 
   already rang associated bells.

Like:

    HEAD, HEAD~1, HEAD~2

If the syntax is changed in the middle (as it was in manual page),
that interrupts the kognitive flow of reading.

    HEAD, HEAD^, HEAD~2

I'm sure when user progresses with his learning, the differences or
similarities of the notations become no-op.

But manual pages are served for wide audience. They are most
important to new users.

I hope we could strive for KISS is possible.
