See the various *-match-p functions in etags.el, which can be used for
that.  You will see in etags-recognize-tags-table that etags.el
programs the order in which the matches are found into the
find-tag-tag-order variable.  We could remove some of the criteria
from that list, preferably under control of some user option, thus
making the results more accurate.
