Arrow keys history also counts empty lines

[ivanjx]

When i tried to use up arrow keys to display the first line again in this example, i need to press it 8 times so it seems like it also counts on the empty lines. Is this intended? Thanks.

Thanks for raising this! Yeah, I wasn't sure which approach was better:

• Trim empty lines from the history
• Leave the user's history untouched, so it matches exactly what the user sees.

I think you're right that we should trim the empty lines; if the user needs an empty line they can always just press ctrl-c, to cancel the current line. I'll see if I can get that implemented over the next few days. Thanks!
