There is a new pull request by classabbyamp against master on the void-packages repository

https://github.com/classabbyamp/void-packages license-show
https://github.com/void-linux/void-packages/pull/41032

common/xbps-src/shutils/show.sh: display `$license` one-per-line
previously, if there was a newline in `$license`, it would not format
properly in `xbps-src show`. This fixes it by splitting it by word and
removing commas and displaying it like some other variables.

fixes #40996

Example:
```
$ ./xbps-src show keepassxc
pkgname:	keepassxc
...
License(s):	GPL-3.0-or-later
License(s):	BSD-3-Clause
License(s):	CC0-1.0
License(s):	LGPL-2.0-only
License(s):	LGPL-2.1-only
License(s):	LGPL-3.0-or-later
License(s):	Nokia-Qt-exception-1.1
License(s):	MIT
License(s):	BSL-1.0
```
