--- Comment #9 from Andreas Schwab <sch...@linux-m68k.org> --- Note that a formal proc argument named "args" is a special case in tcl as it collects all (remaining) arguments as a list. Either the argument needs to be named differently (like "locale") or the proc needs to use [lindex $args 0] to access the first (and only) argument.
