[Bug 1047324] [NEW] dash globbing fails to obey ^

[D J Gardner]

Public bug reported:

Versions known to be affected: 0.5.5.1-3ubuntu2 (lucid)  0.5.7-2ubuntu2
(

In every sane shell I've ever met the glob "[^ab]*" matches everything
except files beginning with a or b.

Current versions of dash ignore the ^ 
(also foo[^~]  only matches foo~) 

For systems that have dash as /bin/sh this breaks every shell script, makefile, etc. that makes use of 
such inverse sets, possibly resulting in destruction of important files. e.g. 
tar -czvf ../foo.tgz *[^~] will  only get the unwanted files.


Demonstration code:
$ mkdir oops ; cd oops ; touch afile bfile cfile ; dash -c 'echo [ab]*' ; dash -c 'echo [^ab]*' ;ls ;  cd ..
afile bfile
afile bfile
afile  bfile  cfile
