Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
If you go back in time in git (eg. git reset, git bisect) then you can
end up in a situation where a file that was generated by a later
version is left around unused in the earlier version.
This isn't a problem for most things, but gobject documentation
generation picks up any file in a directory, even unreferenced ones,
and breaks. So the correct thing to do is to remove these files.
This is a simple renaming of the files/modules.
Note that in OCaml, module names are derived from filenames by
capitalizing the first letter. Thus the old module names had the form
"Generator_api_versions". The new modules names have the form
"Api_versions".
