This isn't something I do ever, but it happened accidentally to me just now and it looked wrong. It looks like it could be related to an earlier issue I had. I have an :au CursorHold to generate tags (although I may remove this, as I have better ideas on how to do it).
Repro steps: 1. visual block select some text (<CTRL-V>) 2. press "r" to replace text 3. wait 'updatetime' Actual: Observe visual mode ending, and selected text being replaced with multiple instances of ^C Expected: Enter some sort of "visual replace" mode. I suspect this is related to the following issue, which Bram explained some months ago. When you move to a new location and very quickly begin some command (like ^W, r, etc) then the command will be aborted because the au for CursorHold runs and issues some command. The one difference is that this new instance of the bug will happen at any time (you can move to a location, wait 20 minutes, visual block select, wait 20 minutes, then press r and it will still happen) I feel that this is a pretty significant bug. My suggested solution would be to disallow the CursorHold au if a command has been started. Cheers! Max
