Well, yes, it is both.

According to my `man isspace':

      The isspace() function tests for the white-space characters.  For any
      locale, this includes the following standard characters:

      ``\t''   ``\n''    ``\v''    ``\f''    ``\r''    `` ''

:-)

The tab (\t) and space characters are linear whitespace (they appear in
a line just as other characters do), and the others are non-linear (they
break that rule somehow).

Indeed. Though in this case, \n is not newline, but linefeed,
semantically. Only on Unix, where \n represents both the carriage return
and the line feed, does it really mean newline. And, in fact, even that
meaning is not 100% right: it actually means EOL--end of line, for it is
used at the very end of a file to mark the end of the last line, even
though there is no new line after it. But we are often sloppy in our
terminology. :-)

I bought myself a typewriter recently. I have a friend who has one, too,
and it allows us to do instant messaging when we go away camping
together, just like when we are at home with our computers.
