Yes, and I think that prompting makes more sense at the time we try to actually revert buffer from disk. Besides this allows to eliminate the first check for modified buffers altogether. And I'd put this (revert some buffers with prompt) into a separate function as I foresee a need for such a function when, say, git-checkout, or any other command that changes working files will be implemented. > I think reverting the file on disk without changing the buffer is > confusing: either you want to discard the changes, and you want to > discard the buffer changes too, or you want to keep your changes, and > reverting the file on disk doesn't make sense since the revert will be > undone as soon as you save the buffer. I think that prompting is the best solution. It won't be a frequent situation, so prompting won't be annoying. Though this will differ both from VC and PCVS behavior. BTW, there is another related issue: what to do with buffers for which their files disappear (are removed). AFAIK PCVS doesn't close such buffers, that according to the above logic is confusing as well. >> In fact I believe the way PCL-CVS handles this, and that was implemented >> in my earlier patch, is superior compared to this patch.

[And so do I, but unlike git-commit, compile has no clue of what files are relevant (though it does lack a method to ignore buffers by, say, regexp of buffer name).] I agree git-commit could be made smarter. Fortunately, save-some-buffers has /pred/ argument that allows for arbitrary filtering of buffers to be considered. -- Sergei. - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
