Merge branch 'jc/log-stdin'
* jc/log-stdin: Add trivial tests for --stdin option to log family Make --stdin option to "log" family read also pathspecs setup_revisions(): do not call get_pathspec() too early Teach --stdin option to "log" family read_revision_from_stdin(): use strbuf Conflicts: revision.c
