Title: Subtracted prefix length from remote terminal width

Subtracted output prefix length from remote pty cols to avoid wrapping output from remote processes designed to use the exact width of the terminal. For example yum (Yellowdog Updater, Modified) uses the entire terminal width to print progress bars. In addition to the output prefix on the host machine, these lines will wrap and cause terrible output.
