Vasil Dimov 8d1675eb7f range-diff: avoid negative string precision ...

If the supplied integer for "precision" is negative in
`"%.*s", len, line` then it is ignored. So the current code is
equivalent to just `"%s", line` because it is executed only if
`len` is negative.

Fix this by saving the value of `len` before overwriting it with the
return value of `parse_git_diff_header()`.
