[RFC PATCH 0/5] git-reset documentation changes

[Thomas Rast]

I wrote this on the bus travelling to France, and haven't got around
to sending it out since then.

The main goal was the first patch, which redoes the 'description'
section in the style pioneered by b831ded (Documentation/checkout:
clarify description, 2010-06-01) in git-checkout(1).

The rest are just various ideas that I'm tossing around.  I also would
like to shorten the 'examples' section significantly if anyone sees a
way to do that without a huge loss of explanations.  I think the
chances that users consult the current version aren't exactly great
because of its length.

[RFC PATCH 1/5] Documentation/git-reset: reorder modes for soft-mixed-hard progression

[Thomas Rast]

Reorder the documetation so that the soft/mixed/hard modes are in this
order.  This way they form a natural progression towards changing more
of the state.

With a careless reading of this paragraph, I got an impression that HEAD
is always affected, but I happen to know that is not the case ;-).

 - "reset" is primarily about resetting the index and the --soft option
   can be used to optionally not to do this.

   . with paths, the command is about fixing up the index contents for
     given specific paths, to prepare for the next commit.  HEAD is not
     moved.

   . without paths, the command is about changing what commit to build
     your next commit on, i.e. HEAD is moved.

The above is a clearer description of "with-path" mode than what we
currently have.  I doubt that we need ", provided that...", though.  

"git reset HEAD frotz" from a head commit without frotz gets rid of frotz
from the index, no?

You're right, I completely left out the <paths> mode there.  I rewrote
this as a short summary of all three modes in this version.

> from the index, no?

True.  I thought it didn't (and required rm --cached) but I must have
mixed up something.

The other patches are unchanged from v1.

-"reset --merge" is meant to be used when resetting out of a conflicted

-involved in the merge does not have local change wrt the index before

-we see some difference between the index and the target and also
