help: don't let tools reflow revlog flags list
Before this change, the text about revlog flags was reflowed into a
single paragraph, which made it a bit hard to read. I don't even know
the rules around this, but adding a blank line before each flag seems
to prevent the reflowing.
help: format revlog.txt more closely to result
The rendered text has spaces before each item in the list
