Thanks!
I completely forgot about `indent-according-to-mode'.

Although note that `c-indent-line-or-region' will behave differently
from `indent-according-to-mode'.

And what is the purpose of `indent-line-ignored-functions'? It is not
very well documented.  The only explanation is in the docstring of
`indent-according-to-mode', which is not very enlightening:

    However, if the value of that
    variable is present in the `indent-line-ignored-functions' variable,
    handle it specially (since those functions are used for tabbing);
    in that case, indent by aligning to the previous non-blank line.

what is "tabbing" in the above?
