num_of_digits() take a size_t instead of a ssize_t, and rename
num_of_digits() to digits()

former in source files; also add an #include guard to proto.h, and make
the config.h #include in nano.h match the config.h #includes everywhere
else

get_next_filename(), use a long instead of an int for the number
prepended to the filename; and in num_of_digits(), use a ssize_t instead
of an int

when HAVE_GETOPT_LONG isn't defined, and rework the special case of
options that are ignored for Pico compatibility so that they display
more neatly when HAVE_GETOPT_LONG isn't defined; in usage(), fix an
erroneous #ifdef that resulted in the -d/--rebinddelete and -k/--cut
options' not being printed when NANO_SMALL was defined
