annotate common/listutil.c @ 285:f23e0ccd5d14

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix call to windows process. This now uses the correct parameters, emits the signals correctly as errors and waits for the process to finish instead of relying on NOASYNC which did not work for runas and also made it impossible to get the return code
