comparison toys/sed.c @ 233:d4176f3f3835

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Zap toys/Config.in and instead create generated/Config.in from contents of toys/*.c. Move relevant info into comment at the top of each toys/*.c. Also convert more of Makefile into a thin wrapper around shell scripts that actually do the work. (Makefile is only still there for the user interface.)
