* maint: git-svn: don't attempt to spawn pager if we don't want one Supplant the "while case ... break ;; esac" idiom User Manual: add a chapter for submodules user-manual: don't assume refs are stored under .git/refs Detect exec bit in more cases. Conjugate "search" correctly in the git-prune-packed man page. Move the paragraph specifying where the .idx and .pack files should be Documentation/git-lost-found.txt: drop unnecessarily duplicated name.
