* [bug] `org-latex-line-break-safe' breaks the export of verse blocks to LaTeX

The recent addition of the `org-latex-line-break-safe' constant makes it
impossible to compile verse blocks. The reason is that now a \\ is
inserted between each stanza (aka each paragraph), instead of the
`\vspace{1em}' as before. That's wrong, as this compile error message
says:

---------
A \newline or \\ command appears between paragraphs, where it makes no
sense. If you're trying to ``leave a blank line'', use a \vspace
command.
---------

You can test yourself with this example:

#+begin_verse
lorem ipsum dolor
lorem ipsum dolor

lorem ipsum dolor
lorem ipsum dolor

lorem ipsum dolor
lorem ipsum dolor
#+end_verse

On the other hand, I have a few reservations about the usefulness of
org-latex-line-break-safe. To begin with, it is a particular solution
applied in a general way. This can have unexpected consequences, as has
happened in verse blocks. It's like putting your whole body in a
cast because of a broken finger.

I think if the reason for this addition is to prevent problems with
square brackets, in certain contexts, why not just apply a point
solution? For example, putting {[}, which is a common LaTeX way to
protect a square bracket. Use a macro, for example, or even
define a new entity, something like:

(setq org-entities-user
      '(("lbrack" "{[}" nil "[" "[" "[" "[")
	("rbrack" "{]}" nil "]" "]" "]" "]")))

And finally, I think that applying a general solution to this problem is
something that should be done(IMHO) in LaTeX and not in Org, for
example, with some new package that would protect certain signs or
through ad hoc LaTeX/Lua code.

Best regards,

Juan Manuel

Only when the separation between stanzas is made by means of a blank
line. With the current behavior of verse blocks in the export to LaTeX,
where the separation between stanzas is done by a \vspace, there is no
problem.

When, months ago, I contributed the LaTeX verse numbering patch, I took
this into account, and it didn't seem like the right time to change the
default behavior of the verse block.

I hope to be able to send a new patch soon in the few days (according to
what we discussed in past messages) where the separation by stanzas is
applied by means of a blank line (which is the right thing to do in
LaTeX). I'm rewriting my old code for verse numbering so that a \\! is
automatically added in the last line of each stanza when line numbering
is on.

Best regards,

Juan Manuel
