Merge branch 'js/read-tree' into js/c-merge-recursive
* js/read-tree: (107 commits)
read-tree: move merge functions to the library
read-trees: refactor the unpack_trees() part
tar-tree: illustrate an obscure feature better
git.c: allow alias expansion without a git directory
setup_git_directory_gently: do not barf when GIT_DIR is given.
Build on Debian GNU/kFreeBSD
Call setup_git_directory() much earlier
Call setup_git_directory() early
Display an error from update-ref if target ref name is invalid.
Fix http-fetch
t4103: fix binary patch application test.
git-apply -R: binary patches are irreversible for now.
Teach git-apply about '-R'
Makefile: ssh-pull.o depends on ssh-fetch.c
log and diff family: honor config even from subdirectories
git-reset: detect update-ref error and report it.
lost-found: use fsck-objects --full
Teach git-http-fetch the --stdin switch
Teach git-local-fetch the --stdin switch
Make pull() support fetching multiple targets at once
