I just realized that changing these lexical rules might have an  
adverse affect on internationalization.  Or it might force more lines  
to go over the 79 character limit.

The problem is that

	_("some string"
	  " and more of it")

is not the same as

	_("some string" +
	  " and more of it")

because the latter won't be extracted by tools like pygettext (I'm  
not sure about standard gettext).  You would either have to teach  
pygettext and maybe gettext about this construct, or you'd have to  
use something different.  Triple quoted strings are probably not so  
good because you'd have to still backslash the trailing newlines.   
You can't split the strings up into sentence fragments because that  
makes some translations impossible.  Someone ease my worries here.
