Nits found in 1.7

I have done a comparison of 1.6 to 1.7 and marked nits that I found.  I have tried to make sure these are all things that Graham could fix himself, but in some cases (about 10% of the comments), I thought Rainer might be interested and might express an opinion–I marked those comments with "(Rainer?)".

I'm posting an FDF (and the corresponding PDF, since it is a recent draft–the FDF will work a lot better with the attached PDF than with some other draft).

I opened another JIRA issue with issues found during this process.

I have fully completed my comparison of 1.6 and 1.7.
