underline is less noticeable than bold, when used on a single character
with completions-first-difference in the "basic" completion style.

In the "basic" completion style completions-first-difference
needs to be more prominent since it's more important to indicate
the next character to type.

Other completion styles don't highlight completions-first-difference
at all.  I'm not sure if only the "basic" completion style highlights
completions-first-difference.

Is it possible to use bold for completions-first-difference only
in the "basic" completion style, but for other completion styles
to use bold for completions-common-part?
