Message:
New patch uploaded, but I'm not totally certain it's correct.  The
message in Documentation/snippets/* is misleading -- you shouldn't edit
them directly (instead, edit stuff in /new/ ), but of course those files
are modified when you run makelsr.py, and those modifications should be
committed to git.

Andrew - don't worry about this.  If nobody finds a significant problem
in the next 24 hours, I'll apply it to my git, run makelsr, and push the
result.

I will change makelsr.py right now to avoid this problem in the future.

Description:
Change keep-inside-line defaults to true.

As discussed in Issue \#1470, the default should be changed so that
good layout with a slight performance hit is the default.
