support fetching into a shallow repository
A shallow commit is a commit which has parents, which in turn are "grafted away", i.e. the commit appears as if it were a root. Since these shallow commits should not be edited by the user, but only by core git, they are recorded in the file $GIT_DIR/shallow. A repository containing shallow commits is called shallow. The advantage of a shallow repository is that even if the upstream contains lots of history, your local (shallow) repository needs not occupy much disk space. The disadvantage is that you might miss a merge base when pulling some remote branch. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
