Nicolas Pitre a883b70d8e tty vt: fix character insertion overflow ... Commit 81732c3b2f ("tty vt: Fix line garbage in virtual console on command line edition") broke insert_char() in multiple ways. Then commit b1a925f44a ("tty vt: Fix a regression in command line edition") partially fixed it. However, the buffer being moved is still too large and overflowing beyond the end of the current line, corrupting existing characters on the next line. Example test case: echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B" Expected result: ab c de Current result: ab c e Needless to say that this is very annoying when inserting words in the middle of paragraphs with certain text editors.
