Few more words;
Patches should clearly apply to bash 4.2 with patchlevel 10.
The problem is with locale specific multibyte characters.
ad 1) User can run command `smůla' (Czech word for bad luck) and bash 
will report:
bash: $'sm\305\257la': command not found

With first patch, it will report:
bash: smůla: command not found

The situation is even worse when you use only non-latin characters.
The second patch handles also situations when word contains 
non-printable characters. For example `"smůla "' (tab after).


I think it will improve look and feel. At least calling isprint() 
function on multibyte characters isn't valid.
