Ok, I've just modified the docstring as these:

DEFUN ("detect-coding-region", Fdetect_coding_region, Sdetect_coding_region,
       2, 3, 0,
       doc: /* Detect coding system of the text in the region between START and 
END.
Return a list of possible coding systems ordered by priority.
The coding systems to try and their priorities follows what
the function `coding-system-priority-list' (which see) returns.
[...]

DEFUN ("coding-system-priority-list", Fcoding_system_priority_list,
       Scoding_system_priority_list, 0, 1, 0,
       doc: /* Return a list of coding systems ordered by their priorities.
The list contains a subset of coding systems; i.e. coding systems
assigned to each coding category (see `coding-category-list').
[...]

Are they clear?  If not, please improve them.
