I've created a seperate thread for this issue, even though I discussed it briefly earlier, as I've done some testing and it seems this may be a Vim bug.
NOTES - using Vim 7.0, downloaded and installed about 2 days ago - running under WinXP SP2 STEPS TO REPRODUCE - fire up "gvim -u NONE -U NONE" - :e foo.txt (actually any file seems to work, regardless of filetype) - press O to open a new line at top of file - type in a single line of gibberish without Enter - hit Esc - press u to undo At this point I should be seeing a diagnostic message in the message line at the bottom, something of the sort "1 more line; after #1 15:17:56", yet I see none. But if I do :messages, it is present. This has been a general problem I've been seeing, undo/redo messages which are not being displayed, or what is more likely, they are being displayed for a split second and then immediately being cleared or over-written (I do occasionally see the message briefly blink before disappearing). This seems to plague predominently single-line changes, like in case above, but it is possible I've seen it at other times too. It is hard to nail down when this does and does not happen. Any fixes or workarounds for this? Can others reproduce this? It's really a minor issue, but it's one of those that, once you notice it happening, it starts driving you mad...
