all: prefer strings.LastIndexByte over strings.LastIndex
strings.LastIndexByte was introduced in go1.5 and it can be used
effectively wherever the second argument to strings.LastIndex is
exactly one byte long.
This avoids generating unnecessary string symbols and saves
a few calls to strings.LastIndex.
