+* ```str``` - string that may contain ANSI CSI SGR sequences
 
 Returns the string length in characters without any ANSI CSI SGR
 sequences contained.

+* ```str``` - a string that may contain ANSI CSI SGR sequences
+* ```width``` - a number representing themaximum number of characters per line
+
+If the string ```str``` is longer than the supplied ```width```,
+splits it into multiple lines on word boundaries to wrap it
+nicely. The resulting string is free of ANSI CSI SGR sequences and may
+contain newline characters.
