Remove disabled readme.txt commandline arguments

[elexis]

While searching for a command, I stumbled upon these command line arguments which were not documented, only pronounced "disabled". The code for these arguments was disabled and/or removed long ago.

I propose to remove the arguments and the remaining commented out code entirely, find out what it did and instead write a good ticket if the tasks are still useful.
