Wrapping on long long-description lines with \x05 doesn't work right

[cpence]

In the long description wrapping code (around here), the line is wrapped to the width of the terminal before the user's provided \x05 escapes are translated to newlines. This means that if you have a really long block of \x05 delimited text, it will get falsely wrapped somewhere in the middle. E.g., the following long description:

Data file types:
\x05- 
\x05Compressed file types:
\x05- gzip (.gz)
\x05- bzip2 (.bz2)
\x05- xz (.xz)
\x05Archive file types:
\x05- tar (.tar, .tar.gz, .tar.bz2, .tar.xz)
\x05- zip (.zip)

will be output to the terminal something like this:

Data file types: 
- 
Compressed file types: 
- gzip (.gz) 
- bzip2 (.bz2) 
- xz (.xz) 
Archive file 
types: 
- tar (.tar, .tar.gz, .tar.bz2, .tar.xz) 
- zip (.zip)

Note the extra wrap between "Archive file" and "types:" -- that's (I presume) 100 characters into the string, the terminal width. If the user's \x05s were converted to newlines before the terminal-width wrapping, this would look right.
