(By *hand*??  Ugh.  We really need a tool that implements some kind of editing 
macros... :-)

Also, I believe make-docfile scans the argument lists; it may need to be taught 
about the new syntax.

Or, the explicit old-style argument declarations can go away, and DEFUN can be 
taught how to expand a list of argument names into a list of new-style argument 
declarations.  I thought about doing this back in May when we were discussing 
the DOC file name handling and version number definition; I think it would 
require making a bunch of helper macros for each MAXARGS value that could get 
passed.  (I was thinking about it in the context of putting the doc strings in 
a section of the executable that only gets paged in when needed on most 
platforms, rather than having to copy them to and then load from a separate 
file.)

They should probably be fixed to be standard variadic functions, which means 
doprnt() has to be taught about va_arg.  I can take a shot at that, if no one 
else feels like it; it's probably easy.


We could also probably ditch the "register" declarations that date back to 
pre-GCC days; do they do *any* good now?
