As it is used by several other tools, better move it outside tools/perf.

-# not it contains a newline.
-#
-# If the text to be wordified contains a newline, then
-# an intrictate shell command substitution is constructed
-# to render the text as a single line; when the shell
-# processes the resulting escaped text, it transforms
-# it into the original unescaped text.
-#
-# If the text does not contain a newline, then this function
-# produces the same results as the `$(shell-sq)' function.
