Bug#466524: bibtex2html: bib2bib fails for field = "text {"}emphase{"} text"

[Samuel Colin <samuel.colin@loria.fr>]

Package: bibtex2html
Version: 1.90-2
Severity: normal


Hello,
bib2bib does not like bib files with the following format:

@InProceedings{somekey,
  author =       "Samuel Colin",
  title =        "A title that {"}confuses{"} bib2bib",
}

bib2bib -c 'author : "Colin"' <this file>
stopped on the first {"}.

The "-delimited fields are a legitimate alternative to {}-delimited 
fields. Furthermore, bibclean seems to prefer the "-delimitation. 

I believe this is because the lexer of bib2bib (and of bibtex2html) does not
handle braces when it has started to read a "-delimited field.

I propose the attached patch to solve the problem.
