# This class quacks like an SSHKit::Formatter, but when any formatting
# methods are called, it simply forwards them to one more more concrete
# formatters. This allows us to split out the responsibilities of
# ConsoleFormatter and LogFileFormatter into two separate classes, with
# DelegatingFormatter forwarding the logging messages to both at once.

# For versions of SSHKit up to and including 1.7.1, the LogfileFormatter

# the stdout and stderr data in the command obj. Therefore, ensure only
# one of the formatters (the last one) gets the original command. This is
# also the formatter whose return value is passed to the caller.
