bug#16781: 24.3; bibtex required fields

[Per Starbäck]

In GNU Emacs 24.3.1,
bibtex-biblatex-entry-alist in lisp/textmodes/bibtex.el tells about
required and optional fields in biblatex, refering to biblatex
documentation.

In the development version of biblatex this was recently changed in the edit
https://github.com/plk/biblatex/commit/b23f504d9138feb4faa2148de6e059d43c43405c

There is actually nothing in biblatex that upholds this distinction
between required and optional arguments, so it's only a documentation
thing, and (as the documentation says), the bibliography styles can
actually handle data very well that lack for example these "required"
fields.

Because of that there's no need to wait for a released version
where this documentation change has taken place, I think. The biblatex
issue is at https://github.com/plk/biblatex/issues/199 for more details
about this.

I'm a bit confused. You talk about both bibtex and biblatex.
bibtex is part of Emacs.
I thought biblatex was part of AUCTeX:
http://git.savannah.gnu.org/cgit/auctex.git/commit/style/biblatex.el

So I'm not sure whose github repository that is, nor why it says: "This
is the current home of biblatex as the status of the author of biblatex
is currently unclear."

Oh, duh, I get it now. You were talking about biblatex; for some
inexplicable reason I thought you were talking about biblatex.el.
I have no idea why I thought that...

I'm glad that confusion is over before I had time to reply.

Since those not into biblatex may wonder if this is the real deal I
should add here that it is indeed. This is what is part of CTAN and what
is distributed to TeX distributions like Tex Live and MikTeX.

My proposed change are about fields there always were optional in
bibtex, and are therefore are omitted in most bib files.

Even though biblatex always have managed without them just as fine as
bibtex its documentation (until now) said they were required, so
bibtex-biblatex-entry-alist requires them, and therefore (with default
settings) refuses to add entries without them.
