The git log doesn't seem to be that informative, either, since
apparently a whole bunch of changes were moved from locales to
iso14651_t1 in:
commit 5d2489928c0040d2a71dd0e63c801f2cf98e7efc

[BZ #672]
2005-01-16 Denis Barbier <barbier@linuxfr.org>
[BZ #672]
* locales/ca_ES: Replace current collation rules by including
iso14651_t1 and adding extra rules if needed. There should be
no noticeable changes in sorted text. only ligatures and
ignoreable characters have modified weights.
* locales/da_DK: Likewise.
* locales/en_CA: Likewise.
* locales/es_US: Likewise.
* locales/fi_FI: Likewise.
* locales/nb_NO: Likewise.
[BZ #672]
* locales/iso14651_t1: Simplified. Extended.
as noted at https://stackoverflow.com/a/34079435/371250 in regards to
schwa in Cyrillic. From a quick skimming the schwa is correctly sorted
in patch 12 for Azeri, Kazakh, Tatar and Turkmen.
