Sorry if I don't closely follow the discussion (I do not know all the
internals of etags.el), and consequently sorry if I am misanderstanding
anything. In that case, please discard my observations below.
I fear I can read in the above quotes a fundamental misunderstanding.
If Emacs (etags.el or anything else) treats implicit tags differently
from explicit tags, that's an error.
Implicit tags are semantically the same as explicit tags. Whether a tag
is implicit or explicit, it's only a matter of efficiency in building
the TAGS file. For a given TAGS file entry, there is either no tag, or
an implicit tag, or an explicit tag. The latter two cases should be
treated exactly alike by whichever program is reading the TAGS file.
Nor is it possible that for a given entry its implicit tag does not
match its explicit tag, because either the former or the latter are
present, not both.
