[PATCH 2/3] docs: remove :c:func: annotations from xarray.rst

[Jonathan Corbet]

Now that the build system automatically marks up function references, we
don't have to clutter the source files, so take it out.

[Some paragraphs could now benefit from refilling, but that was left out to
avoid obscuring the real changes.]

 Each entry will only be returned once, no matter how many indices it
 occupies.
 
-Using :c:func:`xas_next` or :c:func:`xas_prev` with a multi-index xa_state
+Using xas_next() or xas_prev() with a multi-index xa_state
 is not supported.  Using either of these functions on a multi-index entry
 will reveal sibling entries; these should be skipped over by the caller.
