[TxMt] Doc for Tcl mode

Hi

the original command to get man doc from Tcl commands in Tcl mode was broken (at least in my system -with Developer Tools installed) I have simplify it to a simpler and working script borrow from the Shell script mode one:

---------------- word=${TM_SELECTED_TEXT:-$TM_CURRENT_WORD}

try_man () { if man n -w "$word" &>/dev/null; then page=$("$TM_SUPPORT_PATH/bin/html_man.sh" n "$word") echo "<meta http-equiv='Refresh' content='0;URL=tm-file://$page'>" exit_show_html fi }

try_man

echo "Couldn’t find documentation in 'man n' for “${word}”" -----------------
