in gen_bitlen(): on register-starved arches, this is a loss,

Denys Vlasenko 4ebcdf7396 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.
