- Authentication-results: sourceware.org; auth=none
If we submit a command while the prompt cursor is somewhere other than
at the end of the command line, the command line gets truncated as the
command window gets shifted one line up. This happens because we fail
to properly move the cursor to the end of the command line before
transmitting the newline to ncurses. We need to move the cursor because
when ncurses outputs a newline it truncates any text that appears
past the end of the cursor.
* tui/tui-io.c (tui_getc): Move cursor to the end of the command
line before printing a newline.
