This script is used to automatically fix issues within xml documentation
files.
The script is *for now* intended to be used ad-hoc, and the commits to
be examined.
A future discussion will define whether:
* This commit and scripts are kept.
* The script is extended for common use.
The biggest issue right now with the script is that it *could* in theory
destroy a valid space-less varlistentry.
The script could, in practical use, be changed and extended to normalize
some parts of the XML files, mainly:
* A common quoting style for attributes
* Fix-up some weird formatting automatically that xmlformat doesn't
