Sascha, I do understand your concern. Have 25 developers next door :)

Usually, this kind of problem is only about the "process" (name it
development culture, habits, etc).

In many [not only commercial] projects some submit/commit rules are present:
0. Description of the problem it solves
1. We appreciate your patch in "diff -u blah-blah-blah" format
2. It should include man page changes (final or preliminary)
3. Codestyle should conform http://..../
4. Codestyle includes comment rules (usually handled while in review cycle).

Here, from bugzilla, for example:

Each patch/submission always has a code review part. And almost NEVER
gets commited immediately (unless trivial changes).

Writing doxygen/javadoc-like comments is not a big effort: just
purpose of the module, function, arguments and some key notes. It is
more like helping future developers (and author himself, if coming
back to sources after another year of not touching it) with future
maintenance tasks.

Writing a man page is much more serious task. It IS a documentation,
while Doxygen is more like API description/outline.

PS. just my 0.02 UAH for what it worth.
