Good point.  (A url field is not part of standard BibTeX either, but for
sure it belongs to biblatex.)

The (La)TeX meaning of the $ character is relevant for titles that my
contain formulas.  The question is what is in the end more acceptable:
formulas in titles that do not receive special treatment by font-lock.
Or $ being mis-treated in url and file fields (which goes beyond these
fields).  Maybe it is best to let the user decide whether $ should be
treated as math delimiter (the default) or as punctation.
