apply: use starts_with() in gitdiff_verify_name()
Avoid running over the end of line -- a C string whose length is not
known to this function -- by using starts_with() instead of memcmp(3)
for checking if it starts with "/dev/null". Also simply include the
newline in the string constant to compare against. Drop a comment that
just states the obvious.
