hello ,

few days ago i rebuild and reinstalled all pkgsrc packages (cvs from a 
week ago)
but
every now and then i got errors from MC ( midnight commander)
when trying to change to a directory ( mostly when the directory 
contained '-' '_' and such other characters )
after a little google search i found that there used to be a problem 
with the combination of

bash-3.2   ( installed on my system)
echo built in command
mc-4.6.1 (installed , way of managing directory names )


particularly echo changed behavior for echo -e '\nnn'

it seems that :

Bash 3.1 says:   \num    the character whose ASCII code is NUM (octal)
Bash 3.2 says:   \0nnn   the character whose ASCII code is NNN (octal).
                         NNN can be 0 to 3 octal digits


so mc gets choked ,

after a little more search found a patch to fix this (attached)
i tried it for a few hours and it works

could someone have a look on it and if it's ok apply it ?
