comment.
(bibtex-format-field-delimiters): New function, functionality
extracted from bibtex-format-entry.
(bibtex-autokey-get-yearfield-digits): New function, functionality
extracted from bibtex-autokey-get-yearfield.
Completely reimplemented parsing of bibtex
entries in order to avoid stack overflow in the regexp matcher if
field contents become large.

bibtex-end-of-text-in-string): New functions for the parsing of bibtex
entries. Instead of reporting the results of the parsing by
match-beginning or match-end, these functions return data structures
that hold the corresponding positions.
(bibtex-enclosing-field): Changed to also report field boundaries by
return values rather than by match-beginning or match-end. The
following functions have been adapted to use the new parsing
functions.

visible.
Copyright notice is up to date.
Added constant 'bibtex-maintainer-salutation.
(bibtex-mode): use with-temp-buffer rather
than make-temp-name, use match-string-no-properties and eliminate
a quadratic behavior when building bibtex-strings.
(bibtex-reference-key): Accept string entries whose
reference key contains upper case letters.
(bibtex-reference-head): Allow entries to start with
a new line.
Hiding of entry bodies is not longer provided by
bibtex.el directly. Instead the hideshow package can be used.
Added a special bibtex entry to hs-special-modes-alist.
(bibtex-hs-forward-sexp): Added for hideshow.el.
(bibtex-entry-field-alist): Added booktitle field to
proceedings entry type (for cross referencing). Thanks to
Wagner Toledo Correa for the suggestion.

beginning of the comment.
(Fforward_comment): If back_comment fails, go back to the position just
after the comment-end.
(scan_lists): Add comment describing a very minor bug.
to Emacs' syntax. Also fix the comment about set/not-set meanings
since Emacs syntax is not the value 0 any more.
* search.c (compile_pattern_1): Remove RE_CHAR_CLASSES from the syntax
since it's now part of RE_SYNTAX_EMACS.
