Thanks to matley (Luigi Panzeri) for having found the error, i.e. the
escaping of the \n.  Thus, now we've two methods (again, empty lines
added for better reading):
=====
STUMPWM> (defun test-newline-tr ()
  (run-shell-command "echo -e \"Hello,\\n world\" | tr -d '\\n'" t))
TEST-NEWLINE-TR

STUMPWM> (test-newline-tr)
"Hello, world"

STUMPWM> STUMPWM> (defun test-newline-tr ()
  (run-shell-command "echo -e \"Hello,\\n world\" | tr -d \\\\n" t))
STYLE-WARNING: redefining TEST-NEWLINE-TR in DEFUN
TEST-NEWLINE-TR

STUMPWM> (test-newline-tr)
"Hello, world"

STUMPWM>
=====

I'd go for the former, any comments?

Thx, bye,
Gismo / Luca
