dispatch: parse and apply -R early

This allows us to use extensions specified in .hg/hgrc. Unfortunately,
this requires us to parse that file twice, but performance impact on
the version command appears to be less than 1%.

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
