Let's add a very, very important piece of information that was missing:
this thread is from late August 2008. We had deprecated the dashed form
"only for a couple of months" by then (we removed the dashed form from the
completions end of April 2008 in 799596a5d06 (completion: remove use of
dashed git commands, 2008-04-20) for example).

I am glad that you changed your stance from "without dashed builtins, your
Git is broken" to this much more tenable position to state that it may
break super-old promises whose use we discouraged already a full decade

To add some interesting information to this: in MinGit (the light-weight
"Git for applications" we bundle to avoid adding a hefty 230MB to any
application that wants to bundle Git for Windows), we simply ignored that
old promise. We do support hooks written as Unix shell scripts in MinGit,
and we have not had a single report since offering MinGit with v2.9.2 on
July 16th, 2016, that it broke anybody's scripts, so it seems that users
are more sensible than our promises ;-)

Not requiring Git to install any type of link makes it even possible to
bundle it as .zip file (which, let's face it, is the de facto standard for
cross-platform archiving).
