Hi vim team, thank you for developing vim. I discovered the following strange behaviour; seems to be a bug:
Swap file recovery fails, when the only change was adding a one character line. Steps to reproduce: First create a text file OPT.txt to play with (I take a copy of a help page) vim -u NONE :help options :w OPT.txt :q Edit OPT.txt and add a new line just containing x after line 5000 vim -u NONE OPT.txt :5000 ox<Esc> Wait some seconds for the swap file to be written out. Then without having saved, on another terminal kill vim kill -9 <PID> Recover and save the result as new file vim -u NONE -r OPT.txt :w OPT_recovered.txt :q! Diff to see what we got diff -s OPT.txt OPT_recovered.txt What I would expect as output from the diff: 5000a5001 > x What I get instead: 5040a5041 > Lisp mode: When <Enter> is typed in insert mode set the indent for I. e. 40 lines further down any line got duplicated; that is something completely different than what I did (adding the line with the x). I can reproduce this with any play file; you can also create a play file by starting with an empty file and then 10000ohello<Esc> When instead I add two x instead of one oxx<Esc> then everything works fine, and I get as output from the diff 5000a5001 > xx Could you please have a look at it?
