Well, there was talk about indent-region doing like TAB on each
line.  That's a pretty good behavior even when TAB is bound to
indent-relative.

The above is fairly obvious for the case when all lines are
flush-left to begin with, but for programming languages indentation
can also mean to shift towards the left, which indent-relative
doesn't do.

Hm.

Here is an algorithm that describes useful behavior for indent-region
together with indent-relative as the indentation function.  It
assumes that the region does not start or end in the middle of a line.

    * Go to beginning of first line in region.

    * Do back-to-indentation.

    * Remember current column.  Do indent-relative.  Now look by how
      many columns point has moved and call that number of columns N.

    * Do indent-rigidly on the other lines in the region, specifying
      N as ARG (the number of columns to indent).

I guess that this behavior does not fit into the current
indent-region framework.  Hm.
