annotate xrogue/list.c @ 284:6376b514a30b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix more header-related warnings. This fixes all current default warnings with GCC7 on Linux. That does not mean the code is anywhere close to clean.
