No.  It's because it's consistent and makes sense.  That's why every
sane programming language does it this way:

C: s = "foo", strstr(s, "") evaluates to s
C++: string("foo").find("") evaluates to 0
Python: 'foo'.find('') evaluates to 0
Ruby: 'foo'.index('') evaluates to 0
Perl: index("foo", "") evaluates to 0
