Update the function to use the current `.git/modules/` structure, by
only using the basename of the path.
I am not sure when this was changed and too lazy right now to find it
out.
Move `git-track` into its own autoloadable function.
This way it is better maintainable as in one-liner format and brings the
possibility of having more complexity (e.g. for better portability).
By that it is also now executable as `git-spull` as well as `git spull`
as before.
Wrap lines at 80 columns where appropriate and I had the energy to think
about how/where to wrap.
There are still lines longer than that, which I plan to wrap in the
future. But that is enough for now.
Escape slashes in the branch name before passing it to `mktemp`.
Otherwise it would complain with:
mktemp: invalid suffix [...], contains directory separator
Add description in one sentence and use cases for this.
Remove sentence about removing `TEMP_DIR` that is outdated since:
5a8b5ffd21 ("git:checkout-worktree: Use `mktemp` template")
Use a template that directly includes the repository name and the branch
checked out. This makes finding and deleting the worktree directory if
anything goes wrong a lot easier.
Checkout the worktree directly in the temporary directory. With that
`TEMP_DIR` becomes obsolete.
Fix the exit condition when the function is called outside of a git
repository.
Use zsh's `:t` History Expansion Modifier, as `$?` does not keep `git
rev-parse`'s exit code, but rather `basename`'s.
Split `toplevel` definition and assignment as the `local` builtin has
it's own exit code. Thus the function previously did not return if the
`PWD` was not in a git repo.
Some distributions ship older versions of `column` that do not have the
flags `-dNLO`. This is a workaround around this limitation that creates
the same output using other tools.
