If this is a console issue (a problem with layout, rendering, colors, etc.), please post to the console issue tracker.

Seems related to #85

Please fill out the below information:

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.17134.590]

• What you're doing and what's happening: (Copy&paste the full set of specific command-line steps necessary to reproduce the behavior, and their output. Include screen shots if that helps demonstrate the problem.)

Each CASE starts with a freshly started shell window.

CASE 1:

vi /etc/passwd
:colorscheme blue
:q 

• What's wrong / what should be happening instead:
  Expected: Background should be entirely blue, unless syntax highlighting changed it.
  Observed: Blue background stops at the end of each line then returns to native black.

  Expected: on exit screen should return to all black background on return to shell.
  Observed: blue background on characters of bottom line that also returns to native black at EOL.
  New blue background under text are for each new line written.

NOTE: repeating the vi command produces a screen with full blue background, as desired..

CASE 2:
https://github.com/GilbertsHub/web-utils/blob/master/cgibinIntercept.sh

vi cgibinIntercept.sh 
:colorscheme blue
:q 

Expected: background is all blue.
Observed: in this case background is correctly all blue.

Expected: on exit shell window should return to black background.
Observed: same is with CASE 1 exit.
