[src/trunk]: src/usr.bin/xlint/lint1 lint: expand abbreviations in grammar rules



details:   https://anonhg.NetBSD.org/src/rev/eb32334d5c58
branches:  trunk
changeset: 979731:eb32334d5c58

description:
lint: expand abbreviations in grammar rules

stmnt -> statement
comp -> compound

The abbreviation "stmnt" was non-standard, and "comp" was ambiguous
since it is used for "comparison" as well.
