I completely agree. I want a convenient shortcut to use everywhere. > Work is underway on clearing out the issue of forbidden characters in > revision specifiers. We already have commit:file.

One of my ulterior motives for sending this patch was to start a discussion on this topic. I missed the discussion about clearing out forbidden characters so I'll see if I can find it in the archives. Do you happen to have a link? Keep in mind that the syntax that this patch added does not have file~3 = HEAD~3. file~3 means finding file as it existed 3 changes-to-file ago, which is != to HEAD~3 if file did not change in the last 3 commits. It basically runs 'git log -- file' so that only the commits that touch file are considered. Are you suggesting that ~3:file could be the shortcut for this, or would we need a different syntax since you just said that ~3 would be a shortcut for HEAD~3? If there's work on syntax-sugarfying diff/checkout/etc. with these kind of shortcuts then I would like to help out with patches, testing, etc. This is a feature that lots of users would enjoy--I know that for sure. -- David -- 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
