[PATCH] Fix tip-of-the-day with gcc-4.7

[Bill Nottingham]

When making the text file tips-of-the-day, GnuCash expects 'gcc -E' to
preserve at least one of the whitespace lines between entries. However, this
relies on behavior of 'gcc -E' that isn't actually part of the spec, and is
a historical accident. And it changed in gcc-4.7, such that all the
whitespace is removed.

Work around this by explicitly adding a newline in the sed expression.
