Hallo,
in fhandler_console::read1() a short piece of code
ignores CR if it is the one and only char in console input.
I have found no circumstance, in which this code makes sense.
On the other hand: If a process turns stdin into raw mode and
then again into cooked mode, only a single CR is generated by
the return key. In this case, the above mentioned code leads
to the situation, that a getchar doesn't return, if one only
presses the return key!
I want to suggest to kill the mentioned code piece, if nobody
offers a convincing reason to let it in.
Regards,
Corinna
