Currently 'git worktree add' produces output like the following, when
'--no-checkout' is not given:
Preparing foo (identifier foo)
HEAD is now at 26da330922 <title>
where the first line is written to stderr, and the second line coming
from 'git reset --hard' is written to stdout, even though both lines are
supposed to tell the user what has happened. In addition to someone not
familiar with 'git worktree', this might seem as if the current HEAD was
modified, not the HEAD in the new working tree.
If the '--no-checkout' flag is given, the output of 'git worktree add'
is just:
Preparing foo (identifier foo)
even though the HEAD is set to a commit, which is just not checked out.
The identifier is also not particularly relevant for the user at the
moment, as it's only used internally to distinguish between different
worktrees that have the same $(basename <path>).
Fix these inconsistencies, and no longer show the identifier by making
the 'git reset --hard' call not print the "HEAD is now at ..." line
using the newly introduced flag from the previous commit, and printing
the message directly from the builtin command instead.
