>Description:
there are two problems with postcmd
(in both examples postcmd is defined as 'echo -n "^[]2;!#^G"')
1) if FOO is undefined the following error occurs:
lark:~$echo $FOO
FOO: Undefined variable.
Faulty alias 'postcmd' removed.
FOO: Undefined variable.
lark:~$
2) if directory contains only one file and ls is aliased somehow
('alias ls ls' is sufficient) then empty line is printed instead of
file list when doing ls in that directory:

lark:~/foo$alias
postcmd echo -n "^[]2;!#^G"
lark:~/foo$ls
patch-aa
lark:~/foo$alias ls ls
lark:~/foo$alias
ls      ls
postcmd echo -n "^[]2;!#^G"
lark:~/foo$ls

lark:~/foo$
