Don't know. Because: the manual isn't telling the whole truth for -r
anyway. It says that a backslash at EOL does not mean line
continuation. In reality, -r makes *every* backslash be kept.

Ouch. I didn't remember that, even though I already used it...


But still. The docs are wrong (backslashes inside the string). Should
we change the code or the doc?

Neither.

zagzig[271] IFS=$'\n' read -r line <<<'   this has   many   spaces   ' 
zagzig[272] echo %$line%
%   this has   many   spaces   %

} And trailing spaces as well.

Uh-huh.

FW: About word splitting in read (Zsh)

[Andrej Borsenkow]

In (almost latest) CVS:

bor@itsrm2% read -r foo
   qwert   yuiop   !
bor@itsrm2% print -r $foo
qwert   yuiop   !

So, the question is - should we fix -r or introduce new option?
