Yes, I can confirm that describe-text-properties now works as  
describe-function or describe-variable.

But – there seem to be other describe-<whatever> functions which do  
not work like these. Some of these functions produce a [back] key  
only when they are repeated (describe-character-set for example,  
describe-categories, describe-face, describe-fontset) and not when  
they overwrite the contents of the *Help* buffer. Some never seem to  
create this navigation element:

	describe-bindings-internal
	describe-buffer-case-table
	describe-coding-system
	describe-current-coding-system
	describe-current-display-table
	describe-font

The functions describe-minor-mode-from-indicator and describe-minor- 
mode do not show any possible completions...
