[cilkplus-merge] fix various wrapping issues and correct some docs wording

[Aldy Hernandez <aldyh at redhat dot com>]

I am committing the following changes as obvious.  They include some 
wrapping issues, as well as some minor wording issues I found while 
peeking around.

Joseph, I am posting this as an incremental patch, to avoid posting a 7k 
line patch for everything.  I have also asked Balaji to post incremental 
patches as he iterates with you-- at least on these initial style 
reviews-- to aid in reviewing.  Then perhaps after this round is done, 
we can post a toplevel patch once again with everything so far in the 
branch, and start the process again.  If you dislike this approach let 
me know, and we revert to toplevel patches, or perhaps something else.
