(See also the tramp-devel discussion[1].)

Ok, I figured this out. The new loaddefs code was clobbering a regexp 
internally when doing some additional checks while scanning for autoload 
cookies in external package code. That resulted in some autoloads ending 
up in the wrong file. The fix is just to call 'save-match-data' at the 
right spot.

Eli, is this ok for 29.2? It's a small change, and I think is a fairly 
serious regression from 28.
