- A workaround was added for a problem with the "multiline" editor mode which
- occurs when the edit line becomes longer than the terminal's width and the
- terminal cursor is not at position 0 when PS1 is send to the terminal.
- For example: The user executes a $ printf "foo"<enter> # the prompt will start
- at position 3 instead of 0. If the user enters a command which is longer than
- the terminal width and then removes enougth characters that the edit line fits
- again into one line the "foo" at the beginning will be overwritten with the
- prompt.
- The workaround is to add $(printf "%*s\r%s" COLUMNS "") at the beginning of
- PS1 set by /etc/ksh.kshrc, this causes the shell to move to the beginning
- of the next line if the terminal cursor is not at position 0.
