Re: Turning a complete repository to a shallow one

Apparently we could do it:

git clone --single-branch git.git
cd git
git tag -l|xargs git tag -d
git fetch --depth=1 origin master
git repack -ad

I may have been unclear in the earlier message, but this is one of
the reasons why I think "fetch --depth" is misadvertised (it says
"deepen the history", when the real thing it does is to truncate to
the new depth counting from the updated tip), and misdesigned (it
forces the user to guess what the new depth should be).  It should
be advertised correctly, as a way to reset its depth starting from
the current history (and of course --depth=1 is truncates).

We should introduce a separate "fetch --deepen" that does what
normal people would want (see my earlier message with ASCII art).
