Subject: Modify backslash/newline handling for POSIX. We fixed Savannah 16670
 but that broke previously-working makefiles that relied on the GNU make
 behavior.  The POSIX behavior doesn't seem to me to be better, and can be
 obtained using GNU make as well, so put it back as the default behavior and
 require .POSIX to get the POSIX behavior. Add a new section to the manual
 discussing backslash/newline handling. Update the test suite.
