The behavior of auto-indentation within things like <pre>...</pre> (or
here-docs in sh scripts, or strings in other languages, ...) is indeed
not perfect, is inconsistent between major modes, and moreover it's
always clear what is the best behavior.

I think what should happen is:
- indent-region should not modify those lines.
- indent-according-to-mode should not modify those lines either.
- indent-for-tab-command should behave as if in text-mode (i.e. call
  something like indent-relative).

Ideally, this should be recognized and treated as a case of "multiple
major modes" and you should even be able to specify what major mode
to use within the <pre>...</pre> region, so that the indentation there
can be better than text-mode's.
