autosave prevents un-do

[suuuehgi]

The autosave plugin often prevents me from going back through un-do. Un-do works again in these files as soon as I disable the plugin.

what exactly does not work? Please be specific. How do you undo? What exactly happens when you use u to undo? Do you see an error message? What about g+/g- or the :earlier/:later commands?

Also please provide more information: System, vim version, etc.

Please be specific.

I'll do my best!

what exactly does not work?

Pressing u does not undo.

What exactly happens when you use u to undo?

Apparently nothing. I can hold down u without any changes happening. Is there some kind of verbose mode?

Do you see an error message?

No

What about g+/g- or the :earlier/:later commands?

At the moment, I can not reproduce it. It happens sometimes to often during working. I guess, these are the second best bugs.

When I could not undo a crucial edit yesterday, I switched to

augroup autosave
    autocmd!
    autocmd BufRead * if &filetype == "" | setlocal ft=text | endif
    autocmd FileType * autocmd TextChanged,InsertLeave <buffer> if &readonly == 0 | silent write | endif
augroup END

not knowing, what the actual differences are to this plugin.

Also please provide more information: System, vim version, etc.
