I suggest that there would be an option that will make mirc log line colors too (if you /echo 3 asdf then the line color will not be looged, it will if you /echo <Ctrl-K>3asdf) and especially the colors of its own messages.
Also another switch that removes the "Logging started" text.
Why? Because I want my script to reload the logfile on join and display the text exactly as it was when i left irc.
Currently it looks bad
