Bug: org-bibtex-read strips too many braces (8.3.4-39-ge0acd8-elpaplus)

[timor]

When using org-bibtex-read-buffer, I noticed that the following title
field in a bibtex entry:

...
{{MASTER}: {A} {Multicore} {Cache} {Energy}-{Saving}
                  {Technique} {Using} {Dynamic} {Cache}
                  {Reconfiguration}}
...

is read in as

"MASTER}: {A} {Multicore} {Cache} {Energy}-{Saving}
                  {Technique} {Using} {Dynamic} {Cache}
                  {Reconfiguration"

I believe this is due to the duplicate '(123 . 125) element in org-bibtex-read
(org-bibtex.el:634), and was supposed to clean up fields that were
formatted like this:

{{Unnecessary Braces in Title.}}

I do think, however, that the correct behavior would be to only strip
the outer pair of braces.

regards,
timor

So, do you think that returning {Unnecessary Braces in Title.} instead
of the above would be fine?

If that's the case, we could indeed remove the duplicate '(123 . 125).

Yes. Looking at the BibTeX Files I am dealing with, the use of inner
braces is usually justified (except for the example I gave, but it is
not org-mode's job to correct poor BibTeX, I think).  Therefore they
should be kept intact when reading the field.

Very nice.

Inner braces need to be preserved as they are often there to protect
capitalisation, e.g. for TLAs and names like McDonald, but also for
compound names such as {van der Waals} which together form a single
component of a name.  So it's not just the title that needs to be
treated carefully but other entries (author, editor, booktitle).

You are correct.  The piece of code in question is actually called for
all fields, not only title.  I was using the title as an example.  So
if this is changed, it will also preserve the inner braces for all the
other fields.

Done, in master branch.

There are actually no tests for org-bibtex.el. Anyone using this library
(or not!) is more than welcome to write some, BTW.
