These variables seem to have been introduced in [1: 55d1cfe870].  I
agree that it looks like there is no need for them, but I'll wait

author of that commit (and the person mentioned as "suggesting" it) on
CC in case they might remember anything about it.

  Honor the indent-tabs-mode and tab-width setting from user.
