* PageSpecs can now include nested parens, "and", and "or". This remains
backwards compatible to the old GlobList format. It's implemented by
treating the GlobList as a very limited microlanguage that is transformed
to perl code that does the matching.
* The old GlobList format is deprecated, and I encourage users to switch to
using the new PageSpec format. Compatability with the old format will be
removed at some point, possibly by 2.0.
* Wiki rebuild needed on upgrade to this version due to PageSpec change.
* Add support for creation_month and creation_year to PageSpec.
Closes: #380680
* Changes to index file encoding.
