gzip -f zips files with .gz suffix, creating file.gz.gz

[Duncan Sands]

Create a directory containing a file, for example:

 $ mkdir d
 $ touch d/f

Now do (yes, running gzip twice):

 $ gzip -f -r d
 $ gzip -f -r d

Look in the directory and you will find the file a.gz.gz.

 $ cd d
 $ ls
 f.gz.gz

This is a change from ubuntu versions before precise pangolin: previously gzip would
not recompress files ending in .gz when run in this way.

It's a compression conundrum!
Here's a terminal screenshot!

Hi Evan,

I did this and discovered that this tool is buggy :) If you are already logged
into launchpad (as I was) then you don't get the authentification/permission
question in the browser, you just get a message saying you are already logged
in. Logging out then trying again worked.
