ACK

Can be fixed the same way, as my suggestion, but needs one more 
parameter to read_iine_input():

... in ash.c:

read_line_input(..., lookupvar("HOME"), ...)

... and in read_line_input() this must set:

read_line_input(..., char const *homedir, ...)

home_pwd_buf = homedir ? strdup(homedir) : nullstr;


This shall fix your concern, too.
