BugFix: faulty message alignment, cTelnet::postMessage() in non-ERROR cases

Code that was put in to fix messages with tag "[ ERROR ] - " was not copied
to the other tag types, so those messages were not lined up correctly as
per:

"[<tag>] - <message line 1 ...>
           <message line 2 ...>
           ...
           <message line n ...>"
