launching midnight comader (mc) floods history with garbage

[400thecat]

this is histdb output after I have started mc, and opened some jpg file in mc:

  mc
   mc_print_command_buffer () { printf "%s\\n" "$BUFFER" >&12; }
   zle -N mc_print_command_buffer
   bindkey '^[_' mc_print_command_buffer
   mc_print_cursor_position () { echo $CURSOR >&12}
   zle -N mc_print_cursor_position
   bindkey '^[+' mc_print_cursor_position
   _mc_precmd(){ pwd>&10;kill -STOP $$ }; precmd_functions+=(_mc_precmd)
   
   cd "`printf '%b' '\0057tmp'`"
