    1) etags will honour the #line directive by default

    2) if problems will arise, there will be an option to disable this
       behaviour and use the current one instead, where #line is ignored

Those conclusions seem good.

    3) additionally, and as a separate improvement, when told to parse files
       X and Y, where Y contains #line directives pointing to X, do not tag
       X.  This allows to use `etags zz.y zz.c', and etags will only tag
       zz.c, and generate tags pointing to zz.y.

That is backwards.  It should only tag zz.y, not zz.c.

The reason is that zz.y may have tags that are not reflected in zz.c.

                                                  It will also be possible
       to use `etags xx.web xx.c' and etags will only tag xx.c with tags
       pointing to xx.web.

That is reasonable in this case because xx.web is in a format that
can't be processed by etags.
