(Did I break the thread by adding "[PATCH]" to the subject? Apologies
if so, original thread was [1])

The motivation is to allow generating standard "see section
\ref{some-label}" references using org-store/insert-link.

In more detail (repeating/summarizing the prior messages on original thread):

Internal Links stored with org-store-link and inserted with
org-insert-link fail on export for headlines with spaces because of %
encoding the spaces. (This is orthogonal to the patch, just the
original motivation that led to it).

One solution is to use org-id. I also came up with a hack to unhex the
link after it is inserted.

In either case, the links inserted have descriptions. Links with
descriptions always export as hyperref's using the headline text
(instead of regular \ref's using the label).

There is no (?) way to force links with descriptions to export using
regular latex \ref{}'s. John Kitchin offered two workarounds (using a
custom id for every headline or manually \label'ing the headlines and
\ref'ing them instead of using org links).

I had been waffling on whether to switch to the git version of org.
This was motivation to make the switch, so I decided to give a shot at
patching this.

Attached patch introduces `org-latex-prefer-section-references'. If
non-nil, links will use the generated \label even if the link has a

I believe I did everything right - commit message, no failures on make test...
