I can't reproduce this in the current cvs started with -Q.

Please set the following:

(setq bibtex-entry-format
      (append '(opts-or-alts required-fields numerical-fields)
              '(whitespace realign delimiters unify-case)))

I can reproduce this with GNU Emacs 23.0.60.1 (i386-mingw-nt5.1.2600) of
2008-12-14 on BREPNB.

This usually a complete, concise recipe starting from emacs -Q:


emacs -Q --eval "(setq bibtex-entry-format '(delimiters))" file.bib

where file.bib contains:

@misc{foo,
  month=sep # "~21",
}

I've installed a patch that should handle properly concatenated
fields like the above month field. Does it work for you?

Thanks,

Roland

Bug 1907 can be closed.

Fix:

(bibtex-format-entry): For updating field delimiters, allow fields
that are composed of strings and string constants.
