> Yes, I have the problem with using 'cat' on the command line. Only reason I noticed it is when generating CSR's with openssl. Extra spaces are added to the end of certain lines of the CSR after a simple 'cat'. [...]

Marcus, thank you for providing this use case. I was able to replicate this bug
and then it wasn't hard to solve the problem. Screen buffer resize
(enlargement) wasn't handled properly. Screen buffer is initially created at
the size 80x40 characters, but typical konsole window is larger. So this
problem with simple cat command manifested itself just in the space between
line 41 of console till last line of visible screen. Later on, when konsole
scrolls and new lines are added it was ok again. Shortly: bottom lines of newly
opened console and in new space after konsole enlargement.
