I observe problems in this area when changing code (which changes
indentation) and then changing it back (i.e., not undo, but make a

Indeed, that would do it.
In this
case Emacs changes tabs to spaces, assuming the .dir-locals.el settings
already mentioned.
Yup. But it only makes a difference if Arthur hasn't customized
indent-tabs-mode to nil in his Emacs already.
Having a project-wide setting, however, lets us hope that someday the
indentation style will be uniform, and this problem won't occur anymore.
Yes, of course. Here, though, a two-line changed ballooned into a
23-line change. The first 2 lines of the ballooned change were real, and
the other 21 lines were tabs-to-spaces only.
I usually try to undo such hunks with `diff-hl-revert-hunk'.
