It would be nice to be able to print the split diff view with both the left and
right view together like the way they're shown on the screen.
Right now, only local diff can be changed to text, and therefore printed out.
This text is not formatted in a way to show left and right view. When doing CVS
diff, users cannot use different engine and has print disabled.
Since it can be wasteful to print all stuffs out, provide options to show all
text, diff and some text, or diff only view.
Please also allow export the side by side diff to html, so that users can also
print and view/share them if needed (for both local diff, and cvs diff).
