One long standing annoyance I have with using vim-tags is that our tags file is not properly sorted. That is, the sorting exhuberant Ctags does is only on the tag itself. The problem with that is that, for example, the tag 'mutex' appears a mere 505 times, 492 of those are structure members. However it is _far_ more likely that someone wants the struct definition when looking for the mutex tag than any of those members. However, due to the nature of the sorting, the struct definition will not be first. So add a script that does a custom sort of the tags file, taking the tag kind into account. The kind ordering is roughly: 'type', 'function', 'macro', 'enum', rest.
