I don't know if it matters, but this definition of xstrndup, like the version
in commit.c, doesn't match the definition of strndup.  strndup duplicates a
string, copying up to n characters or the length of the string.  This xstrndup
always copies n characters, reading past the end of the string if it doesn't
have at least n characters.
