[2152292] Corrected implementation of uuencoding.
Add back -wrapchar option to "binary encode uuencode".
Hm, this check doesn't really add anything.
And the decoder too.
Add back -wrapchar option to "binary encode uuencode"
Be careful: separator needs to be bytes, not internal-encoded.
Refactor to remove unused flexibility.
small improvements to the documentation
ChangeLog entry
[2152292]: Corrected implementation of uuencode handling to support line length
indicator bytes.

***POTENTIAL INCOMPATIBILITY***
Existing code that was using the old versions and working around the
limitations will now need to do far less. The -maxlen option now has strict
limits on the range of supported lengths; this is a limitation of the format
itself.
