Hmm, it almost makes sense to do something of the sort:

int alpm_add_target(pmtrans_t *trans, const char *pkgname)
{
   ...
   if(is_ignored(pkgname)) {
      return PM_ERR_PKG_IGNORED;
   }
   ...
}


if(alpm_add_target(trans, "xorg-video-something") == PM_ERR_PKG_IGNORED) {
   puts("omg the package was ignored, panic panic!");
}

At least, that is how I'd think it through.
