Getting tab copy and paste right with rxvt-unicode option

I  have always liked xterm, but moved to rxvt years ago for a couple of its features.  Recently I moved to urxvt256c for all my terminal needs.
When I use the AWS cli tools, which output tabs as whitespace, my double click selection has started including the tabs.  Maybe it has done this for a while, I don't know exactly when it started, but it is annoying since a double click selection which grabs a tab can screw up a command line paste if there is 1 file in the directory.
So you get:

ssh $(i2ip thisisthe1localfile.txt i-1234567)

instead of

ssh $(i2ip i-1234567)

thanks to bash's autocomplete.
After some googling I found what I should have found originally:

https://github.com/jhelwig/rxvt-unicode-ppa/blob/master/doc/rxvt.1.pod

-ptab|+ptabIf enabled (default), "Horizontal Tab" characters are being stored as actual wide characters in the screen buffer, which makes it possible to select and paste them. Since a horizontal tab is a cursor movement and not an actual glyph, this can sometimes be visually annoying as the cursor on a tab character is displayed as a wide cursor; resource pastableTabs.

adding +ptab seems to have fixed it.
Now my urxvt start script looks like this:
