Subject: apply --whitespace=error: correctly report new blank lines at end
Earlier 77b15bb (apply --whitespace=warn/error: diagnose blank at EOF,
2009-09-03) cheated by reporting the line number of the hunk that contains
the offending line that adds new blank lines at the end of the file. All
other types of whitespace errors are reported with the line number in the
patch file that has the actual offending text.

* This is an interim workaround. fragment->linenr was added for the
specific purpose of reporting this type of error in the quoted patch,
and the field is not used for any other purpose, so it may be a better
fix to either rename it to hunk_linenr and use it directly without
introducing a new local variable in apply_one_fragment(), or pass
"linenr" as a parameter to parse_fragment() and pass it down the
callchain all the way through, or something like that.
