Update.

2000-02-24  Geoff Clare  <gwc@unisoft.com>

	* posix/wordexp-test.c: Updated to include tests for all the
	problems fixed by the last changes to wordexp.c.

	* posix/wordexp.c: Use $HOME to expand ~ (if set); fix off-by-one
	error in expansion of ~user; correct handling of WRDE_APPEND and
	WRDE_DOOFFS; return WRDE_SYNTAX for syntax errors in command
	substitutions; limit removal of newlines to those that are
	really `trailing'; allow for current word to continue after
	a command substitution (e.g. "a$(echo b)c"); restore pwordexp
	members properly on error returns.
