comparison main.c @ 122:64c4de3709de

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Complain if -[DIU] is given an empty argument. (Like many compilers over the years, we don't accept the argument appearing in the next argv word.) Warn about this in the man page too.
