This reverts commit 46ddc11a8be79515b4ab9f9f7568c3d624ac72fe. The change is good in master but became subtly broken during the backport to rocko. Either the path passed to file should be quoted using double quotes (with any " chars in the path being escaped) or the path should be quoted using single quotes (and then any " chars in the path should NOT be escaped). Escaping " chars and using single quotes will cause problems for filenames containing " chars.
