Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
C++: Include the old style function support even when lambdas are available. This allows old style applications to compile unmodified on lambda supported compilers. Also include the original extremely simple test program in dwtestoo.cpp so non-lambda compilers will see something besides a build failure. Add a message to the old sample to upgrade to a lambda supported compiler to see the full sample application.
