Use colors to show the counterexamples and the derivations in color,
to highlight their structure. Align the outputs, and add i18n
support. Reduce width by using a one-space separator instead of
two-space.
From
Example A • B C
First derivation s ::=[ a ::=[ A • ] x ::=[ B C ] ]
Second derivation s ::=[ y ::=[ A • B ] c ::=[ C ] ]
to
Example A • B C
First derivation s ::=[ a ::=[ A • ] x ::=[ B C ] ]
Example A • B C
Second derivation s ::=[ y ::=[ A • B ] c ::=[ C ] ]
with colors.
