Subject: [PATCH] add *--no-merges* flag to suppress display of merge commits
Message-ID: <Pine.LNX.4.63.0508081136210.31438@wgmdd8.biozentrum.uni-wuerzburg.de>

```
As requested by Junio (who suggested --single-parents-only, but this
could forget a no-parent root).

Also, adds a few missing options to the usage string.
