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.
