* Autoload debugging

*
5 
* The internal __autoload() function of the shell-wrapper has two hooks.
6 
* The first is called before the include is done, the second afterwards.
7 
*
8 
* we use it to track the order the includes are handled. That makes it
9 
* easier to find implicit dependency problems.

*
11 
* :set autoloaddebug = on
12 
* :set autoloaddebug = off
13 
*
14 
* the depth functions track the recursive depth of the includes. The
15 
* wrapper uses it to print the dots at the beginning of the line.
