Subject: [PATCH] Hi, This patch adds the warning Anton requested,
 -=------------------------=-------------------------------> WARNING: Every
 sanity checks passed and only the DANGEROUS operations left. Please make sure
 all your important data had been backed up in case of an unexpected failure!
 Are you sure you want to proceed (y/[n])? OK quitting. NO CHANGES has been
 made to your NTFS volume.
 <----------------------------------------------------------The question will
 be skipped if the -f (force) used [e.g. for automatic testing]. This patch
 needs the earlier sent ntfsresize-usage-cleanup.diff patch.	Szaka

(Logical change 1.11)
