jim: fix bug in tcl "puts"

tcl "puts" didn't work because the logging code sensored strings
that did not include a '\n'. The correct thing is to sensor
empty strings, which are used to keep gdb connection alive.

The tcl "puts" code broke apart strings which do contain '\n' in
order to implement the -nonewline argument, which is how it
got hurt by the bug in log.c
