annotate rogue4/xstr.c @ 104:fbc75509f4cd

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add config.h to the list of headers in the Makefiles. Some .o files need to be rebuilt if config.h changes. Adding it to the list of headers may still fail to solve the problem, because some of the Makefiles use implicit rules or do not list dependencies properly.
