Hmm
1) in minimal configuration have setup without
BB_FEATURE_GETUSERNAME_AND_HOMEDIR
2) usage gethostaname() is very strange for default configure setup prompt
3) in your patch variable `l' not used.

In my opinion, \W is not suitable for use ;-)
Also, current sh have many-many other lame problem, you improvements is
crazy in compare with this ;-)
