Hi Paul, But now that I am thinking about this, it occurs to me that maybe the two methods can be collapsed into one:
just make the sequence to be inserted for folding be (using ABNF):
"\" %x0C [%x0A] *" " ["\"]
The trailing backslash only needs to be inserted if the character following it is a space or backslash. (IOW it is *optional* if the next character is *not* space or backslash.)
So, when removing the folding, upon finding ("\" %x0C [%x0A] *" ") you remove that and if there is then a backslash remove that too.
Are you suggesting a hybrid approach where, within a folded file, a line may be folded one way one the other based on context? Would that detract from readability?
FWIW, I just posted -08 that adds forced-folding support to the single-backslash strategy as well as a couple forced folding examples.
Thank you for requesting these examples, as an issue in the `rfcfold` script was found and fixed.
