Previously most devices would lose the character before a line wrap. The log's text rendering was starting at offset 4 but none of the arithmetic was taking this into account. It just happened to work on the Nexus 9's 1536-pixel wide display (1536/18=85.3) but not on a device such as the Nexus 5 (1080/18=60). The only active part of this change is the change from 4 to 0 in the gr_text call. The rest is just a few bits of trivial cleanup while I was working out what was going on.
