A recommended way to move trees between repositories is to use
git-filter-branch to revise the history for a single tree:
However, this can lead to "argument list too long" errors when the
original repository has many retained branches (>6k)
/usr/local/git/libexec/git-core/git-filter-branch: line 270:
/usr/local/git/libexec/git-core/git: Argument list too long
Could not get the commits
Saving the output from rev-parse and feeding it into rev-list from
its standard input avoids this problem, since the rev-parse output
is not processed as a command line argument.
