The variable bibtex-string-files tells bibtex.el where it can find the
string definitions (which are then stored in the variable
bibtex-strings).  This complements bibtex-files that tells bibtex.el
where it can find the BibTeX entries.  A command like
bibtex-search-entry searches the entries in the files in bibtex-files.
