annotate anagram/agcore/bpu.h @ 21:1c9dac05d040

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add lint-style FALLTHROUGH annotations to fallthrough cases. (in the parse engine and thus the output code) Document this, because the old output causes warnings with gcc10.
