Updated the wawk grammar in a way where semicolon usage is now more consistent:
there are no longer weird cases where some "{" blocks "}" require a semicolon after them, while others do not: now none of them require semicolons, but they (as well as other statements) can have as many semicolons after them as they like
BREAKING CHANGE: if/else statements that DO NOT use blocks but one-line statements instead, now require semicolons for each statement, and not just the last one.
