Not answered.

This is not an excuse, it's an explanation. Previously I cared about the
dissectors and tried to make sure that the pidl generated dissectors were
changed at the source. So it was manually monitored because this happened
time and again.

Actually it is quite easy to miss: Opening a file at a specific line
(first match of some RE) or running an automated script on a file.

Of course it is some sort of lazyness. But without that lazyness even more
patches remain unapplied (which is another of your complaints). What we
need is some way to notice that we are patching a generated file or to make
sure we "can't" modify generated files. Your email caused a thread on how
to fix this problem *reliably* on wireshark-dev.

So I need to check out a huge code base to just get a small tool? How about
moving pidl into a sub-git that can be ckecked out without needing to check
out the whole of samba?

As you are one of the people who are quite likely to know best what is
amiss with that page, the solution with the least total time invested
in the correction would probably be that you correct that page.
