[issue1134] qrefresh looses metadata in some specific conditions

[Philippe Biondi]

New submission from Philippe Biondi <phil at secdev.org>:

qrefresh sometimes looses meta-data (like hg copy). It seems to happen when it's
quicker to patch from /dev/null than from the original file. This does not
happen on the last file.

$ hg init
$ echo -e "a\nb\nc\nd\ne" > foo
$ hg add
adding foo
$ hg commit -m 'foo'
$ hg qnew bar
$ hg cp foo foo2
$ hg cp foo foo3
$ vi foo2 # remove some lines
$ vi foo3 # remove some lines
$ hg qdiff
diff --git a/foo b/foo2
copy from foo
copy to foo2
--- a/foo
