The first tag is a named tag, as described in etc/ETAGS.EBNF. Why do
you say it is incorrect? Does etags.el behave badly with that tag?
While the automatically generated explicit tag name should do no harm,
if you generate a moreappropriate tag name that should improve
functionality. In this case, I suspect that the tag name should be in
fact "unravel_univ" rather than "pred unravel_univ".
In short:
1) the first tag is anamed tag, and should behave essentially like the
second, probably providing more resilience against code changes, so
it shuld be the preferred way to generate a tag
2) this can be further improved with knowledge of the tagged langage:
rather than relying on etags to autometically generate a name, the
code should ideally provide the correct name
