apt-ftparchive release generates broken Release file

[Joe Cooper]

Turns out this was a bug in apt-ftparchive that leads to a space before 
the MD5SUM section (the docs also don't explain that Release has to be 
built out-of-path to leave itself out of the Release file).  I'll see if 
this bug has already been noted at Launchpad or upstream, and if not, 
I'll file one.

The workaround is to manually remove the extra space between the Release 
description fields and MD5Sum: (and to generate Release outside of the 
root directory and move it into place after generating it).
