fix(renderer): restore tab stops if hard tabs are enabled

[aymanbagabas]

When hard tabs are enabled, we optimize rendering by using actual tab characters instead of spaces. This requires us to set tab stops every 8 columns at the beginning of the rendering process.

Fixes: #1614
Supersedes: #1647
