Description

patch -p0 -E --dry-run prints "checking file " for the new version of patch(2.7.1) rather than "patching file" as it did for older versions. This causes TMP2 to become empty, which causes the script to hang on this command forever:
PREFIX_DIRS_AND_FILES=$(cut -d '/' -f 1 | sort | uniq)
