bug(fmt): semicolon insertion causing syntax errors with using in a for-of loop

[nberlette]

Version: Deno 1.44.4+dadc606 (macOS 14.5, M1 Pro)

When a for-of loop contains a using statement instead of let or const, deno fmt inserts a semicolon after the identifier in the middle of the statement, breaking it half and creating a syntax error.

I haven't had a chance to test different combinations of for-of/for-await-of loops nor await using. I also haven't had a chance to test it with semicolons disabled in fmt config, but I would assume that configuration would likely prevent this from happening.

Here's a quick recording of it occuring in VSCode as described:
