Garbage characters displayed in prompt on Ubuntu 14.04

I have the PS Core alpha 11 installed. When PowerShell starts, my prompt looks like this:

As soon as I type a single character l in this case, the prompt changes to:

The erroneous 1 displayed has nothing to do with the history id I display in my prompt. For instance, if my history was at 2, as soon as I type the 1 reappears.

After I execute the command the prompt is displayed correctly again until I start typing a new command.

Is this related to the prompt function getting invoked twice?

I don't know. I'll experiment with this some tomorrow when I'm back on this VM. It is interesting that the garbage glyph appears to be 001B which is the hex value of the \e char. It's still too bad <backtick>e didn't get added to PowerShell along with <backtick>uXXXX e.g. `u001b.

Yup, the prompt is getting invoked twice. Not sure if that is what is causing the garbage char.

Here is my prompt func (using a hacked version of posh-git that runs on PS Core and returns an ANSI seq string instead of writing to host):

Most likely a dupe of #468, reopen with additional information if you disagree.
