Babel 12.2.x test failures due to no-breaking spaces

[hroncok]

Hello, in Fedora we are updating our babel to 12.2.0 and I noticed some test failures of flask-babel. To reproduce:

[flask-babel (master *)]$ git diff

This looks like a change from a SPACE to NARROW NO-BREAK SPACE in babel output.

This is just a friendly heads-up for you, I don't expect you to do anything.
