"Tilde Expansion" is part of the ieee 1003.1-2001 posix standard that was
just released a few weeks ago by the Open Group and IEEE, as well as the
Unix98 and Unix95 standards (ieee 1003.1-1990). This encorporates Unix
specs 1, 2 and 3, so it has been a standard for over ten years.
As we have been talking about the use of ksh88 with Solaris as the default
shell, that was written before the posix 1003.1-1990 standard was
released.
