comparison vdp.c @ 1170:9170fc4d9835

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Don't adjust cycles every frame. Only when we start getting close to UINT_MAX. Don't adjust all the way down to zero when we do adjust. Shouldn't fix anything, but may make debugging current issues easier.
