How to maintain Exec output after exit of inner Exec process ?

[raphaelvigee]

When into exec mode, execs will print a bunch of things to stdout, when the process exits and returns control to bbt, bbt will wipe the output, how to maintain what was previously outputed ?

I believe the fix is as simple as

diff --git a/exec.go b/exec.go
index 7a14d2a..2dbc1f9 100644
--- a/exec.go
+++ b/exec.go
@@ -121,6 +121,8 @@ func (p *Program) exec(c ExecCommand, fn ExecCallback) {
                return
        }

+       p.renderer.(*standardRenderer).linesRendered = 0
+
        // Have the program re-capture input.
        err := p.RestoreTerminal()
        if fn != nil {

would this be worth adding to the renderer interface ? (resetLinesRendered()) ?
