Rollup merge of #32509 - tclfs:patch-2, r=steveklabnik 

docs: make some text changes on Section `Macros`

(1) In contrast to `that`, `so that` expresses `result` indicated by the sentence, not `reason`;
(2) `block` is an expression, and may be have an expression, so I add `optionally an expression` to make more precise;
~~(3) When I read here, I was confused with what `the child` referred to. After modification, it would be better.~~
