+=============================
+
+The check looks for long integral constants and inserts the digits separator
+(') appropriately. Groupings:
+ - decimal integral constants, groups of 3 digits, e.g. int x = 1'000;
+ - binary integral constants, groups of 4 digits, e.g. int x = 0b0010'0011;
+ - octal integral constants, groups of 3 digits, e.g. int x = 0377'777;
+ - hexadecimal integral constants, groups of 4 digits, e.g. unsigned long
+ x = 0xffff'0000;
+ - floating-point constants, group into 3 digits on either side of the
+ decimal point, e.g. float x = 3'456.001'25f;
