Add a space after a period in docs

[swissspidy]

Thanks for the patch! Introduced in [9138].

It looks like the docblock can be further improved. For example, the default value should be at the end of the parameter description, not at the beginning. Also, the default value for the other params isn't documented.

Adjusted the docs in 37732.2.diff​ according to our ​PHP documentation standards.

Thanks @swissspidy ! It seems periods are missed of $before and after.

[swissspidy]

Oh yeah, you're right. Thanks!
