   daemon is started.

See Below was confusing because it linked to the entire documentation section.
This provides a direct link to the section explaining why TCP over TCP is a bad idea.

* Make hostwatch locale-independent

See #377: hostwatch used to call netstat and parse the result,
without setting the locale.
The problem is converting the binary output to a unicode string,
as the locale may be utf-8, latin-1, or literally anything.
Setting the locale to C avoids this issue, as netstat's source
strings to not use non-ASCII characters.

* Break line, check all other invocations

This commit resolves #297, allowing the buffers used in the latency control to be changed with a command line option ‘--latency-buffer-size’.

We do this by changing a module variable in ssnet.py (similar to the MAX_CHANNEL variable) which seems to be the simplest code change without extensive hacking.

Documentation is also updated.

The changes in a765aa32 removed a more complex pieced of code for parsing which sudo command to use. The %(eb)s no longer refers to any variable and is directly printed to the command line.

%(eb)s is now replaced with ‘sudo’.

Latest version of attrs breaks pytest, see:

Regression was introduced in #337 that is skipping all local traffic,
including DNS. This change makes UDP port 53 (DNS) LOCAL traffic to be
treated as special case.

Fixes #357

In certain cases socket.connect fails with ECONNABORTED, which is
treated as "unknown" error causing sshuttle to crash.

Fixes #356

`pacman -Sy` does a partial upgrade, which is specifically documented as being unsupported.

Correct the install flag for arch linux installation example.
