I came across this thread after making a simple argparse formatter for
preserving paragraphs. The submissions here look better than that effort. Here
is a quick, hacky look at the patches from one perspective.
I wanted to prefer ParagraphFormatterML, but didn't like that it doesn't appear
to wrap bullet lines, and it wrapped help and epilogs to different lengths. For
all options I found an initial textwrap.dedent() was needed to get the results
I expected. When I did the dedent with ParagraphFormatter*, a subsequent
textwrap.indent(" ") hack was needed to restore spaces at the wrap point.
FlexiFormatter was incomplete - epilogs weren't affected.
Ultimately, I settled on reworking FlexiFormatter. My version has the following
changes:
- Refactor the formatting code out a la ParagraphFormatter, and add to
_fill_text() as well, so formatting is available for both epilogs and option
help
- Add a leading textwrap.dedent(), to get it to feel more like HelpFormatter.
Note
- The result requires line feed escapes within paragraphs.
- I'm not using the "indent" argument for _fill_text(), with no apparent
consequences.
- Automated tests show that FlexiFormatter adds a space to each blank line. I
decided that was not a problem
Code is at:

Regarding licensing, my contributions (and presumably the others') is addressed
by the CLA.
I'd very much like to see something from this thread merged. This looks to me
to be good enough. Any objections to a pull request?
