[elpa] externals/org b93a61af9c 1/2: org-latex-line-break-safe: Use safer value of "\\[0pt]"

[ELPA Syncer]

branch: externals/org
commit b93a61af9c93d21c56cf883630e52f36076e40bd
Author: Ihor Radchenko <yantar92@posteo.net>
Commit: Ihor Radchenko <yantar92@posteo.net>

    org-latex-line-break-safe: Use safer value of "\\[0pt]"
    
    * lisp/ox-latex.el (org-latex-line-break-safe):
    (org-latex-table-row):
    Change \empty ending to explicit optional argument.  \empty still has
    undesired side effects in some cases.
    
    * testing/lisp/test-org-table.el (test-org-table/to-latex):
    * testing/lisp/test-ox-latex.el (test-ox-latex/verse): Update tests.
