some reformatting (5 of 4)

Take care of most of include/*.h.  I punted on extern.h.

For both src/*.c and include/*.h, I used mismatched checks of
width > 79 to decide which files to look at and then width > 78
to decide which lines to maybe revise, so I didn't look at a bunch
of the files.

I don't plan to go back and do it right.  Shortening lines that are
80 or wider to less than 80 is the significant part.  Otherwise
emacs puts a backslash in column 80 and the rest of the line of text
on the next line of the screen, making things harder to read.

include/sndprocs.h
