Hi Paul,
Thanks for your comments!
1) Section 6.2 recommends only using double backslash folding if
single backslash folding doesn't work. But all the examples in section
9 violate this.
True, but these example illustrate the algorithm itself, and so seem
okay, or is your suggestion to add text stating this?
My suggestion is to use an example that would force the use of double
backslash folding. This would mean that the the examples wouldn't be for
the same text, but I don't think that is a problem. This would allow you
to show the various forms that force use of double backslash folding.
FWIW, the `rfcfold` script in the appendix of the draft was used on all
the examples in Section 9. By default, the `rfcfold` script follows the
recommendation (i.e., single before double), but also accepts a
command-line option to specify the folding strategy to use. For the
examples in section 9, this command-line option was used.
2) Regarding forced folding in section 8.2.1: step 1 (Determine where
the fold will occur) could benefit from some elaboration regarding
lines that require forced folding. In particular, when an input line
flagged for forced folding ends in backslash, then it must indeed be
folded before the last character, while in all other cases it can be
folded at any position prior to the max line length. (While this is
obvious if you think about it, some might miss this.)
Your comment goes to step 1, are you suggesting a modification such as
the following?
OLD
1. Determine where the fold will occur. This location MUST be
before or at the desired maximum column.
NEW
1. Determine where the fold will occur. This location MUST be
before or at the desired maximum column. In the case of a forced
folding, the location MUST be before or at the end of the line.
Not quite. I think:
1. Determine where the fold will occur. This location MUST be
before or at the desired maximum column. This (of course) MUST be prior
to the last character on the line. In the case of a forced folding, this
may precede the desired maximum column.
(Or do you want to allow the degenerate case where the line is folded at
the end, so the continuation contains nothing?)
Also, there should be examples of forced folding.
Agreed.
If forced folding example(s) are *added* then I think it is fine to
retain the existing example done both ways.
Thanks,
Paul
