record: edit patch of newly added files (issue4304) I tried to fix this issue in the past and had to revert the fix. This is a second attempt without the regression we found with the first one. record defines special headers (of file) as headers whose hunk are not shown to the user for editing, they are used to represent deleted, moved and new files. Since we want to authorize editing the patch of newly added file we make the newly added file with some content not special anymore. This entails that we have to save their content before applying the backup to be able to revert it if the patch does not apply properly. We reintroduce the test showing that newly added files can be edited and that their content is shown to the user.
