bug#4717: 23.1.50; C-M-h in bibtex mode

[Chong Yidong]

Hi Roland,

Could you take a look at this bug?  There seems to be no good reason for
bibtex to behave differently than the rest of Emacs.  What bibtex-mode
probably needs to do is to bind beginning/end-of-defun-function to
bibtex-beginning/end-of-entry.  Then you can remove bibtex-mark-entry
(or rather make it an obsolete alias for mark-defun).

WDYT?
