annotate rogue3/save.c @ 229:50b89f165a34

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use uniform return types for functions related to options. Functions for printing options now return void. Functions for setting options now return int. Argument types still vary, though converting all the option pointers to void* would be possible.
