[regression] editor: indent button is never enabled

[Becky Gibson]

I used to be able to use the indent button to indent list items but now the indent button is never enabled.

run dijit/tests/test_Editor.html select all of the text in the first editor an delete it click on the bullet list button create three bullets:

• one
• two
• three

put the cursor at the beginning of two. Click the indent button - note that it is marked as unavailable and clicking it does nothing. I should be able to indent an existing list item

This seems related to the change for #6408 / [13262]

adding a return in richtext._sCall() seems to fix this - can anyone think of any consequences to adding the return? This used to work even after the [13262] changes.

(In [15244]) fixes #7632. When _sCall() was added as a wrapper to dojo.withGlobal() the return was neglected. Some callers rely on the return value to set a variable. That was the case for indent. Solution was add a return to sCall().
