Re: Bug: [patch] Fix org-babel-result-to-file never expanding links when babel is evaluated in indirect buffer [9.3.7 (release_9.3.7-728-g1efc4e @ /home/yantar92/.emacs.d/straight/build/org/)]

[John Herrlin <jherrlin@gmail.com>]

It's intended to change directory and dont clone base buffer values. I
tried to accomplish "If the `default-directory' is different from the
containing file's directory then expand relative links." As I
understands it that's when it inserts a relative link, otherwise it just
`result'. I was looking from the indirect buffers point of view and from
there the relative link is off in this case. But from the base buffers
point of view everything works fine. I guess that it was my use case
that is strange.

Looks good!

Best regards
John
