Fix copyright date with SOURCE_DATE_EPOCH set

QuLogic · QuLogic · commit 20f0f767393a · 2021-11-23T03:58:52.000-05:00
When `SOURCE_DATE_EPOCH` is set, then Sphinx will attempt to 'fix' the year in the copyright: sphinx-doc/sphinx#3451 (comment) We already correctly understand that envvar, so this is unexpected and wrong. Sphinx looks for a 4-digit year followed by a space or two 4-digit years separated by a dash. We can fix this by using an en-dash, which is the correct typographical symbol for date ranges anyway, and thwarts Sphinx. Fixes matplotlib#20854
