Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
srogue: don't store machine-dependent metadata in the savefile. Super-Rogue, like Rogue V4, stored data of machine-dependent length in the savefile, to prevent cheating. This made saved games non-portable. Also deleted was a check that used this data, and prevented restoring savefiles from backup. This change BREAKS SAVEFILE COMPATIBILITY, but old files can be converted by removing the block at offset 0x1e with length sizeof(ino_t) + sizeof(dev_t) + 2 * sizeof(time_t). That seems to be 0x14 on i686 and 0x20 on x86_64.
