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.
