* cc/sha1-bsearch: (95 commits) patch-ids: use the new generic "sha1_pos" function to lookup sha1 sha1-lookup: add new "sha1_pos" function to efficiently lookup sha1 Update draft release notes to 1.6.3 GIT 1.6.2.2 send-email: ensure quoted addresses are rfc2047 encoded send-email: correct two tests which were going interactive Documentation: git-svn: fix trunk/fetch svn-remote key typo Mailmap: Allow empty email addresses to be mapped Cleanup warning about known issues in cvsimport documentation Documentation: Remove an odd "instead" send-email: ask_default should apply to all emails, not just the first send-email: don't attempt to prompt if tty is closed fix portability problem with IS_RUN_COMMAND_ERR Documentation: use "spurious .sp" XSLT if DOCBOOK_SUPPRESS_SP is set mailmap: resurrect lower-casing of email addresses builtin-clone.c: no need to strdup for setenv builtin-clone.c: make junk_pid static git-svn: add a double quiet option to hide git commits Update draft release notes to 1.6.2.2 Documentation: push.default applies to all remotes ...
