revlog: generate trivial deltas against null revision To avoid extra memory usage and performance issues with large files, generate a trivial delta header for deltas against the null revision rather than calling the usual delta generator. We append the delta header to meta rather than prepending it to data to avoid a large allocate and copy.

hg falabala [OPTION]... [FILE]...

use 'echo' to diff repository (or selected files)

            Show differences between revisions for the specified
            files, using the 'echo' program.

            When two revision arguments are given, then changes are
            shown between those revisions. If only one revision is
            specified then that revision is compared to the working
            directory, and, when no revisions are specified, the
            working directory files are compared to its parent.

options:

 -o --option   pass option to comparison program
 -r --rev      revision
 -I --include  include names matching the given patterns
 -X --exclude  exclude names matching the given patterns

use "hg -v help falabala" to show global options
