With the latest patch it's optional, enabled by 'completions-detailed',
but an additional option could be added - specific to grouping only
in read-char-by-name.

This is a problem.  I tried TAB with tab-width=3, but some characters
are still wider than 3.  Then I tried 'char-width' on these characters,
but 'char-width' returns 1 for wide characters.  This is strange,
I expected it to return 4 for characters wider than tab-width=3.
