Description:
Prompt expansion of \W sometimes produces garbage prompts.

Repeat-By:
$ PS1='\W$ '
~$ cd /home
hmee$ cd /proc
pocc$ cd /lib32
li332$

Fix:
In parse.y : decode_prompt_string() in the 'W' case, it uses strcpy
to copy the basename of the path to the beginning of the string.
For short strings, the src and dest args to strcpy may overlap
which is not supported by strcpy.

memmove should be used instead.

change
strcpy (t_string, t + 1);
to
memmove (t_string, t + 1, strlen(t + 1) + 1);

(untested)

[BUG] Bash does not properly check for return value of tiocgpgrp() or ioctl(TIOCGPGRP)
