Automatically wrap lines created by changesgenerate and default to name and email

[luc14n0]

This should bring us closer to how osc vc behaves:

BEFORE:

-------------------------------------------------------------------
Fri Feb 10 02:14:14 UTC 2023 - [email protected]

- Update to version 1.17.0+8:
  * add an optional parameter to _p9k_upglob to pass glob qualifiers and use it in most cases to restrict globbing to files/directories/links/etc (#2175)
  * set POWERLEVEL9K_VPN_IP_INTERFACE to the same value as the default: this adds ZeroTier support
  * fix the default value of POWERLEVEL9K_VPN_IP_INTERFACE
  * fix a silly bug introduced in the last commit (#2170)
  * fix network interface detection on macos (#2170)
  * bust caches
  * Add AWS partitions support to EKS kubernetes cluster names
  * Update README.md
  * don't trust P9K_SSH if it was set with a different TTY (#2154)
  * work around a bug in ohmyzsh (#2152)

The module in use here is textwrap and it's part of Python's Standard Library, so there's no need for extra dependencies. And unless there's a word longer than 67 characters or a hyphened compound word, words shouldn't get split.

The modifications I did to SystemExit() should look like this, for the changesauthor:

No 'changesauthor' has been defined! You can do it by:                                                             [4/128]
                              
Configuring:                                                                                                              
    * The 'realname' entry for the default API section (api.opensuse.org) -- or whatever OBS
      instance you're working with -- in your OSCRC file with:
                              
        osc config "https://api.opensuse.org" realname John "Doe"

    * The '<param name="changesauthor">John Doe</param> tag nested under the obs_scm/tar_scm
      service tag in your _service file.

Passing:
    * '--changesauthor "John Doe"' on the CLI, when using the obs_scm/tar_scm script manually.

And for the newly introduced changesemail parameter:

No 'changesemail' has been defined! You can do it by:

Configuring:
    * The 'email' entry for the default API section (api.opensuse.org) -- or whatever OBS
      instance you're working with -- in your OSCRC file with:

        osc config "https://api.opensuse.org" email "[email protected]"

    * The '<param name="changesemail">[email protected]</param> tag nested under the
      obs_scm/tar_scm service tag in your _service file.

Passing:
    * '--changesemail "[email protected]"' on the CLI, when using the obs_scm/tar_scm script
      manually.

There's only one issue with one of my last iterations. When using the service in the CLI fails:

I don't know why the commit messages aren't being written to the temporary .changes file yet.

Another ping!

In #502 I implemented the real name handling differently, like osc vc does
