Ok. Then what about
(defun string-strip (str)
"Return a copy of STR with leading and trailing white space removed."
(save-match-data
(string-match
"\\`[[:space:]\n]*\\(\\(?:.\\|\n\\)*?\\)[[:space:]\n]*\\'" str)
(match-string 1 str)))
(string-strip " foo ") => "foo"
(string-strip " \nfoo\n ") => "foo"
(string-strip " foo\nbar ") => "foo\nbar"
(string-strip " ") => ""
(string-strip " \n ") => ""
