IS_PREFIX is prefix a prefix of path?

canonicalization and normalization are NOT performed duplicated slashes are dropped

function s = is_prefix(prefix, pth)
arguments
  prefix {mustBeTextScalar}
  pth {mustBeTextScalar}
end

pr = stdlib.drop_slash(prefix);
p = stdlib.drop_slash(pth);

Lp = strlength(p);

s = Lp && startsWith(p, pr) && (Lp >= strlength(pr));

end
