Commits that weren't read from git-rev-list, i.e. the ones displayed with an open circle, were displayed incorrectly: the headline was null if there was only one line, and the commit comment was put all on one line. Also, the terminal commits weren't displayed when -r was used. Signed-off-by: Paul Mackerras <paulus@samba.org>
