However, be warned that trailing spaces and tabs disable it as a line
continuation character.  I got caught by an editor that inserted such
things and then denied their existence :-(  Also, note that it possible
to have two legal programs that differ only in the presence or absence
of trailings spaces ....

And thirdly and most horribly, note that the standard does not define
how non-trivial end-of-line indicators are represented.  For example,
does the concept end-of-line-with-form-feed translate into '\f\n' or
'\n\f'?  The former is implied by the relevant character set standards
(i.e. ASCII and its successors), and the latter is implied by ANSI C.

Yuck.
