--soft::
Does not touch the index file nor the working tree at all, but
requires them to be in a good order. This leaves all your changed
- files "Changes to be committed", as 'git-status' would
+ files "Changes to be committed", as 'git status' would
put it.
--hard::
and updates the files that are different between the named commit
and the current commit in the working tree.
+--keep::
+ Reset the index to the given commit, keeping local changes in
+ the working tree since the current commit, while updating
+ working tree files without local changes to what appears in
+ the given commit. If a file that is different between the
+ current commit and the given commit has local changes, reset
+ is aborted.

"reset --merge" is meant to be used when resetting out of a conflicted
merge. Any mergy operation guarantees that the work tree file that is
resetting out from a state that a mergy operation left after failing
with a conflict. That is why we disallow --merge option in this case.
+"reset --keep" is meant to be used when removing some of the last
+commits in the current branch while keeping changes in the working
+tree. If there could be conflicts between the changes in the commit we
+want to remove and the changes in the working tree we want to keep,
+the reset is disallowed. That's why it is disallowed if there are both
+changes between the working tree and HEAD, and between HEAD and the
+target. To be safe, it is also disallowed when there are unmerged
+entries.
+
The following tables show what happens when there are unmerged
entries:
--mixed X B B
--hard B B B
--merge B B B
+ --keep (disallowed)
working index HEAD target working index HEAD
----------------------------------------------------
--mixed X A A
--hard A A A
--merge A A A
+ --keep (disallowed)
X means any state and U means an unmerged index.
<2> This commits all other changes in the index.
<3> Adds the file to the index again.
+Keep changes in working tree while discarding some previous commits::
++
+Suppose you are working on something and you commit it, and then you
+continue working a bit more, but now you think that what you have in
+your working tree should be in another branch that has nothing to do
+with what you commited previously. You can start a new branch and
+reset it while keeping the changes in your work tree.
++
+------------
+$ git tag start
+$ git checkout -b branch1
+$ edit
+$ git commit ... <1>
+$ edit
+$ git checkout -b branch2 <2>
+$ git reset --keep start <3>
+------------
++
+<1> This commits your first edits in branch1.
+<2> In the ideal world, you could have realized that the earlier
+ commit did not belong to the new topic when you created and switched
+ to branch2 (i.e. "git checkout -b branch2 start"), but nobody is
+ perfect.
+<3> But you can use "reset --keep" to remove the unwanted commit after
+ you switched to "branch2".
