What to do about utility functions that are in .c files?  The post above 
says the 'initial idea'.  So, should we wait to see how that pans out? 
And that later the facility will be extended, if possible, to separately 
compiled .o's.  Or should those functions be moved to a header that is 
included only by the .c's that use the function, such as foo_inline.h ?

As I said earlier, I have a candidate function, regcurly that once was 
static but when toke.c started using it in addition to regcomp, that had 
to be changed, and there are places where its code is duplicated instead 
of calling it.
