[IMP] *: remove "French spacing" 👺

According to Wiktionary, French spacing is "the archaic practice (though
still current in French) of inserting a space around colons, semicolons,
question marks, and exclamation marks". This is not standard practice in
English and most languages of the world.

The purpose of this commit is to start purging the code from this typo,
as it may reflect poorly on the software for some people.
