Merge remote-tracking branch 'ko/maint' into jc/diff-index-quick-exit-early
* ko/maint: (4352 commits) git-submodule.sh: separate parens by a space to avoid confusing some shells Documentation/technical/api-diff.txt: correct name of diff_unmerge() read_gitfile_gently: use ssize_t to hold read result remove tests of always-false condition rerere.c: diagnose a corrupt MERGE_RR when hitting EOF between TAB and '\0' Git 1.7.5.3 init/clone: remove short option -L and document --separate-git-dir do not read beyond end of malloc'd buffer git-svn: Fix git svn log --show-commit Git 1.7.5.2 provide a copy of the LGPLv2.1 test core.gitproxy configuration copy_gecos: fix not adding nlen to len when processing "&" Update draft release notes to 1.7.5.2 Documentation/git-fsck.txt: fix typo: unreadable -> unreachable send-pack: avoid deadlock on git:// push with failed pack-objects connect: let callers know if connection is a socket connect: treat generic proxy processes like ssh processes sideband_demux(): fix decl-after-stmt t3503: test cherry picking and reverting root commits ...
