Eric Sunshine 5c942570fe worktree: add: suppress auto-vivication with --detach and no <branch>
Fix oversight where branch auto-vivication incorrectly kicks in when
--detach is specified and <branch> omitted. Instead, treat:

    git worktree add --detach <path>

as shorthand for:

    git worktree add --detach <path> HEAD

Eric Sunshine ab0b2c53ed worktree: make --detach mutually exclusive with -b/-B
Be consistent with git-checkout which disallows this (not particularly
meaningful) combination.

Eric Sunshine 5dd6e234a7 worktree: introduce options container
add_worktree() will eventually need to deal with some options itself, so
introduce a structure into which options can be conveniently bundled,
and pass it along to add_worktree().

Eric Sunshine eef005dcb3 worktree: simplify new branch (-b/-B) option checking
Make 'new_branch' be the name of the new branch for both forced and
non-forced cases; and add boolean 'force_new_branch' to indicate forced
branch creation. This will simplify logic later on when git-worktree
handles branch creation locally rather than delegating it to
git-checkout as part of the worktree population phase.

Eric Sunshine cd2f471311 worktree: improve worktree setup message
When git-worktree creates a new worktree, it reports:

    Enter "<path>" (identifier <tag>)

which misleadingly implies that it is setting <path> as the working
directory (as if "cd <path>" had been invoked), whereas it's actually
preparing the new worktree by creating its administrative files, setting
HEAD, and populating it. Make this more clear by instead saying:

    Preparing "<path>" (identifier <tag>)

Junio C Hamano c925fe2368 Revert "checkout: retire --ignore-other-worktrees in favor of --force"
This reverts commit 0d1a151783.

When trying to switch to a different branch, that happens to be
checked out in another working tree, the user shouldn't have to
give up the other safety measures (like protecting the local changes
that overlap the difference between the branches) while defeating
the "no two checkouts of the same branch" safety.

Eric Sunshine 0d1a151783 checkout: retire --ignore-other-worktrees in favor of --force
As a safeguard, checking out a branch already checked out by a different
worktree is disallowed. This behavior can be overridden with
--ignore-other-worktrees, however, this option is neither obvious nor
particularly discoverable. As a common safeguard override, --force is
more likely to come to mind. Therefore, overload it to also suppress the
check for a branch already checked out elsewhere.

Eric Sunshine 1eb07d829f worktree: add: auto-vivify new branch when <branch> is omitted
As a convenience, when <branch> is omitted from "git worktree <path>
<branch>" and neither -b nor -B is used, automatically create a new
branch named after <path>, as if "-b $(basename <path>)" was specified.
Thus, "git worktree add ../hotfix" creates a new branch named "hotfix"
and associates it with new worktree "../hotfix".

Eric Sunshine f5682b2a86 worktree: extract basename computation to new function
A subsequent patch will also need to compute the basename of the new
worktree, so factor out this logic into a new function.

Eric Sunshine b979d95027 checkout: retire --to option
Now that "git worktree add" has achieved user-facing feature-parity with
"git checkout --to", retire the latter.

Move the actual linked worktree creation functionality,
prepare_linked_checkout() and its helpers, verbatim from checkout.c to
worktree.c.

This effectively reverts changes to checkout.c by 529fef2 (checkout:
support checking out into a new working directory, 2014-11-30) with the
exception of merge_working_tree() and switch_branches() which still
require specialized knowledge that a the checkout is occurring in a
newly-created linked worktree (signaled to them by the private
GIT_CHECKOUT_NEW_WORKTREE environment variable).

Eric Sunshine cbdf60fa18 worktree: add -b/-B options
One of git-worktree's roles is to populate the new worktree, much like
git-checkout, and thus, for convenience, ought to support several of the
same shortcuts. Toward this goal, add -b/-B options to create a new
branch and check it out in the new worktree.

(For brevity, only -b is mentioned in the synopsis; -B is omitted.)

Eric Sunshine fc56361f58 worktree: introduce "add" command
The plan is to relocate "git checkout --to" functionality to "git
worktree add". As a first step, introduce a bare-bones git-worktree
"add" command along with documentation. At this stage, "git worktree
add" merely invokes "git checkout --to" behind the scenes, but an
upcoming patch will move the actual functionality
(checkout.c:prepare_linked_checkout() and its helpers) to worktree.c.

Nguyễn Thái Ngọc Duy df0b6cfbda worktree: new place for "git prune --worktrees"
Commit 23af91d (prune: strategies for linked checkouts - 2014-11-30)
adds "--worktrees" to "git prune" without realizing that "git prune" is
for object database only. This patch moves the same functionality to a
new command "git worktree".
