Merge branch 'master' into lj/refs
* master: (72 commits) runstatus: do not recurse into subdirectories if not needed grep: fix --fixed-strings combined with expression. grep: free expressions and patterns when done. Corrected copy-and-paste thinko in ignore executable bit test case. An illustration of rev-list --parents --pretty=raw Allow git-checkout when on a non-existant branch. gitweb: Decode long title for link tooltips git-svn: Fix fetch --no-ignore-externals with GIT_SVN_NO_LIB=1 Ignore executable bit when adding files if filemode=0. Remove empty ref directories that prevent creating a ref. Use const for interpolate arguments git-archive: update documentation Deprecate merge-recursive.py gitweb: fix over-eager application of esc_html(). Allow '(no author)' in git-svn's authors file. Allow 'svn fetch' on '(no date)' revisions in Subversion. git-repack: allow git-repack to run in subdirectory Remove upload-tar and make git-tar-tree a thin wrapper to git-archive git-tar-tree: Move code for git-archive --format=tar to archive-tar.c git-tar-tree: Remove duplicate git_config() call ...
