Ok, will do from here on out.  With respect to the discussion about flags, I 
did not know that scripts/auxiliar/ was not part of the automated 
build process, and now that I do, I will make sure to run it when making any 
doc changes.
I think that your idea of having some way to automatically check the docs is 
great.  It is important that developers, as best as possible, update the docs 
to work after their syntax changes.  However, without automatic checks, it is 

In my opinion, the best way to do this would be to have a catalog of properties 
and public functions used in the docs.  Whenever a developer:

1)  Eliminates a function; or
2)  Eliminates a property; or
3)  Changes the return value of the property (i.e. ly:grob? becomes boolean?),

make doc will be scanned and the build will crash if;

1) The eliminated function still exists in the docs; or
2) The eliminated property still exists in the docs; or
3) The return value requested in the docs no longer reflects the new return 
value of the property.

As for syntax changes, I agree with you about a general rule being 
inappropriate and that avoiding them is very important.  I think that the above 
type of doc checking is likely the best way to handle syntax changes, and 
otherwise, the review process can be the forum for deciding their 
appropriateness.  In the case of my most recent two pushes (Flag and Stem 
changes), the syntax changes were the subject of the discussion surrounding the 
patches, so I think that the review process did its job.
