The reason why I thought it was a more grave problem is because (1)
gets 7648757 out of (2), which gets 2297783817 (that is, among the
2.2 billion paths that appear in various GitHub public repositories,
a tad short of 8 million paths have '+' somewhere):
(1) SELECT count(*) FROM `bigquery-public-data.github_repos.files`
where path like '%+%';
(2) SELECT count(*) FROM `bigquery-public-data.github_repos.files`;
If you drop the technique MSYS2 borrowed from Cygwin to support
these characters NTFS does not like by mapping them to a private
page, wouldn't it mean that these projects cannot be used with Git
for Windows? Are we going to bug each of these projects to change
their pathnames?
If that is not the case, then that's fine.
FWIW, I am OK with moving away from '+' in *our* project; that is
easy enough to do, and such a change does not have to make the end
result visually less pleasing, as long as we pick a good substitute
suffix. Is '~' (or ',') allowed on NTFS, for example? The point of
'+' being short, sweet, and easy to spot, I'd rather not to use
'.<anyword>' if we can avoid it.
Whatever suffix we choose, we need to be aware that the pattern is
not limited to Documentation/ directory, so at least the top level
.gitignore and Makefile in various subdirectories need vetting.
