Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Merge of r4944: removed GLOB_NOSORT glob option. This will result in alphabetical sorting of included files if the "include" directive with wildcards is used. Note that the behaviour is now different from that on Windows, where alphabetical sorting is not guaranteed for FindFirsFile()/FindNextFile() (used to be alphabetical on NTFS, but not on FAT). Approved by Igor Sysoev, prodded by many.
