b0320eaf6a git-reset: Let -q hush "locally modified" messages
"git reset -q" is advertised to "only report errors", but "locally
modified" messages are still shown.  They are not errors but diagnostics.

d14e7407b3 "needs update" considered harmful
"git update-index --refresh", "git reset" and "git add --refresh" have
reported paths that have local modifications as "needs update" since the
beginning of git.

Although this is logically correct in that you need to update the index at
that path before you can commit that change, it is now becoming more and
more clear, especially with the continuous push for user friendliness
since 1.5.0 series, that the message is suboptimal.  After all, the change
may be something the user might want to get rid of, and "updating" would
be absolutely a wrong thing to do if that is the case.

I prepared two alternatives to solve this.  Both aim to reword the message
to more neutral "locally modified".

This patch is a more intrusive variant that changes the message for only
Porcelain commands ("add" and "reset") while keeping the plumbing
"update-index" intact.

1b1dd23f2d Make usage strings dash-less
When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form.  So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.

This patch makes git commands show the dash-less version.

For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

dfc8f39e43 Allow "git-reset path" when unambiguous
Resetting a selected set of index entries is done with
"git reset -- paths" syntax, but we did not allow -- to be omitted
even when the command is unambiguous.

This updates the command to follow the general rule:

 * When -- appears, revs come before it, and paths come after it;

 * When there is no --, earlier ones are revs and the rest are paths, and
   we need to guess.  When lack of -- marker forces us to guess, we
   protect from user errors and typoes by making sure what we treat as
   revs do not appear as filenames in the work tree, and what we treat as
   paths do appear as filenames in the work tree, and by erroring out if
   that is not the case.  We tell the user to disambiguate by using -- in
   such a case.

which is employed elsewhere in the system.

When this rule is applied to "reset", because we can have only zero or one
rev to the command, the check can be slightly simpler than other programs.
We have to check only the first one or two tokens after the command name
and options, and when they are:

    -- A:
    	no explicit rev given; "A" and whatever follows it are paths.

    A --:
        explicit rev "A" given and whatever follows the "--" are paths.

    A B:
       "A" could be rev or path and we need to guess.  "B" could
       be missing but if exists that (and everything that follows) would
       be paths.

So we apply the guess only in the last case and only to "A" (not "B" and
what comes after it).

 * As long as "A" is unambiguously a path, index entries for "A", "B" (and
   everything that follows) are reset to the HEAD revision.

 * If "A" is unambiguously a rev, on the other hand, the index entries for
   "B" (and everything that follows) are reset to the "A" revision.

ef90d6d420 Provide git_config with a callback-data parameter
git_config() only had a function parameter, but no callback data
parameter.  This assumes that all callback functions only modify
global variables.

With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

2efb3b0617 Clean up find_unique_abbrev() callers
Now find_unique_abbrev() never returns NULL, there is no need for callers
to prepare for seeing NULL and fall back to giving the full 40-hexdigits.

While we are at it, drop "..." in the "git reset" output that reports the
location of the new HEAD, between the abbreviated commit object name and
the one line commit summary.  Because we are always showing the HEAD
(which cannot be missing!), we never had a case where we show the full 40
hexdigits that is not followed by three dots, and these three dots were
stealing 3 columns from the precious horizontal screen real estate out of
80 that can better be used for the one line commit summary.

2e7a9785c2 git-reset: do not be confused if there is nothing to reset
The purpose of the function update_index_from_diff() (which is the
callback function we give do_diff_cache()) is to update those index
entries which differ from the given commit.

Since do_diff_cache() plays games with the in-memory index, this function
discarded the cache and reread it.

Then, back in the function read_from_tree() we wrote the index.

Of course, this broke down when there were no changes and
update_index_from_diff() was not called, and therefore the mangled index
was not discarded.

The solution is to move the index writing into the function
update_index_from_diff().

Noticed by Björn Steinbrink.

0e5a7faa3a Make "git reset" a builtin.
This replaces the script "git-reset.sh" with "builtin-reset.c".

A few git commands used in the script are called from the builtin also:
"ls-files" to check for unmerged files, "read-tree" for resetting
the index file in "mixed" and "hard" resets, and "update-index" to
refresh at the end in the "mixed" reset and also for the option that
gets selected paths into the index.

The reset option with paths was implemented by Johannes Schindelin.

Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.

The following table shows the behaviour of "git reset" for
the different supported options, where X means "changing"
the HEAD, index or working tree:

reset:  --soft  --mixed  --hard  -- <paths>
HEAD       X       X        X        -
index      -       X        X        X
files      -       -        X        -
