From: Vasil Dimov <vd@xxxxxxxxxxx>
If the supplied integer for "precisoin" 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()`.
