diff gen/statements.c @ 82:d8dd47ef3973 trunk

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
[svn r86] Changed the way arguments are given storage. It is now detected if they will need it during semantic passes. Initial support for debug information. Very limited, but MUCH better than nothing :)
