modeHelp eats blank lines

Open simonmichael opened this issue 8 years ago • 1 comments

I have a mode-building helper that wants to show multiple blank-line-separated paragraphs of help text, above the cmdargs-generated flags/subcommands help. This means using modeHelp, not modeHelpSuffix, but it seems blank lines in modeHelp are always removed. How about a PR to change that ?

I mean: would a PR to stop this behaviour be welcome ? (Or if you change it before I figure out how, even better.)

And if the former... I guess a Test11 failure on mac with GHC 8.2 is expected ?

$ stack exec -- cmdargs --test
