I'm not picking on anyone in particular here, just noticing that some stuff 
that really shouldn't have changed is quite often getting "touched" due to 
changes to svn:mergeinfo.

For example, if I look at the revision log for boost/config.hpp in the 
release branch I see:

As well as cluttering up the revision logs, this often leads to property 
and/or tree conflicts when merging your own stuff, and I can't tell you how 
annoying that is to figure out! :-(
BTW, my sincere apologies to Eric here - he just happened to be the latest 
culprit - can some SVN guru suggest how to prevent this sort of spurious 
changing going on?
BTW2, lest this turn into "my extra advanced version control system doesn't 
do messy stuff like this" conversation - I'm sure you're correct - some 
other version control system probably doesn't have this trap - but I sure 
bet it has other traps just as annoying for the unwary.  Just saying....
Thanks, John.
