[BUG] [PATCH] org-odt-plain-text: Fix when text contains only spaces [9.7-pre (release_9.6.4-346-g7d41bd @ /home/cassou/.emacs.d/lib/org/lisp/)]

[Damien Cassou]

Hi,

in [1], Ihor fixed a bug I reported in ox-odt. Unfortunately, this fix
broke figures with several lines of captions such as:

    #+CAPTION: first line,
    #+CAPTION: second line
    [[file:media/myPicture.png]]

This is because, in this case, org-odt-plain-text is called at some
point with " " as value for `text`. In this context, both `leading` and
`trailing` temporary variables contain the same value as `text`, making
the `substring` call crash.

The attached patch fixes the issue by considering that there is no
leading/trailing content when the input only contains spaces.

Best
