RE: FW: [gnu.org #371319] missing in documentation?

[Meller, Thomas]

Hello Jim,

thanks a lot for your help.
Meanwhile I found my way through.

My experience with the texinfo manuals is most of them repeat the
content of the corresponding manpages.
Well - experiences are subject to aging. :-| 
Times get better - sometimes. :)
Simply adding the hint "info coreutils 'date invocation' " near the
explanation of the '-d' switch would help a lot.
I don't think it is necessary to export the texinfo manual. If you find
something worth learning how to fiddle with 'info' and don't use it -
that's up to you.

New features are always welcome. Finding them, too.

terrible Unicode shattering fold(1) command

[jidanni]

Problem 1: Here we see fold -s busy busting apart UTF-8 characters
again still.

Every third chop falls on a boundary, so is lucky.

No, I did not use `--bytes'. The result is the same as if I did anyway!

Problem 2: Also, when the critical chunk moves past the chopper blade, and we 
now start
chopping ASCII, the UTF-8 chopping subsides, but it still chops NOT at
a blank, yes, that agrees with

`--spaces'
 Break at word boundaries: the line is broken after the last blank
 before the maximum line length.  If the line contains no such
 blanks, the line is broken at the maximum line length as usual.

but don't you see **you leave no option open to respect peoples words
and not bust them apart**. "So don't use the program" you might say.
Well, the program works nicely on 99% of the lines. Just please add an
option to also not bust apart peoples words no matter what!

fmt -s does not have this problem.
fold with no -s, and no -b or with -b also busts Unicode, use this
shortened test where the blade hits the critical area. Therefore we
see -b is stuck on, like it or not.
