A field "file" is, I believe, not part of standard BibTeX. So the above
is somewhat pushing the limits of BibTeX mode.
>From a more practical perspective, I need to say that the above problem
reaches the limits of my knowledge of how font-lock works in general and
how it deals with the (La)TeX delimiter "$" in particular. Occassionally,
unpaired "$" give me strange results in LaTeX documents, though I have
no recipe to illustrate this.
I believe the above problem would require that BibTeX mode first parses
the BibTeX entries. Then it uses different syntax tables for normal
fields and the file field. I do not know how feasable this is, in
particular with larger BibTeX files.
I added Stefan to the CCs. Long time ago, he helped me with font-lock
for BibTeX mode. Maybe he has some comments.
Personally, I use a completely different strategy for associating file
names with BibTeX entries: the BibTeX autokey machinery generates the
nondirectory part of the filename that I associate with an entry. And
find-dired locates the file, whereever it resides under a certain
directory. So there is no file field at all that would require
maintenance.
