hush: remove code to track PS1/2 values dynamically - it's too much work
Assignments / exports / unsets of variables are far more frequent than prompt printing, and if we show prompt, we are likely to be limited by user typing speed - do not optimize for that scenario. Just re-query $PS1 / $PS2 values when need to show the prompt. function old new delta fgetc_interactive 236 259 +23 set_vars_and_save_old 150 147 -3 pseudo_exec_argv 597 594 -3 hush_main 1110 1105 -5 enter_var_nest_level 38 32 -6 builtin_local 56 50 -6 run_pipe 1857 1834 -23 leave_var_nest_level 127 98 -29 handle_changed_special_names 111 79 -32 cmdedit_update_prompt 57 - -57 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 1/8 up/down: 23/-164) Total: -141 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
