bug#39255: small inconsistency in reftex-get-bib-names

[Benedikt Tissot]

Hello,

I just wanted to point out that `reftex-get-bib-names` returns only the
last names for most cases of author fields, but for fields of the form
"Firstname Middlename Lastname" all names are returned.
If you think that this should be changed, simply adding another regexp
(after beginning and trailing whitespaces are removed, ie. after line
453 or 455) of the form
(while (string-match "^[\\.a-zA-Z\\-]+[ \t]+" names)
                    (setq names (replace-match "" nil t names)))
removes the first (and middlenames) in all remaining cases I could
think of.

Thanks for maintaining auctex.
Best Regards,
Benedikt
