annotate tests/agcl/ffcalc/number.h @ 22:5581ef01f993

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Regen all the AG output. This also fixes the line number output in the tools (cgbigen/helpgen/help2html), apparently because those files weren't regenerated last go.
