Amir E. Aharoni a9208a08ab (bug 25277) Moved the space before the dirmark.
If the dirmark is immediately adjacent to the file name, the user
may copy it with and then paste an unneeded dirmark somewhere.
It can be adjacent to the file description, however.

Patch set 2: using getDirMarkEntity, according to MaxSem's suggestion.
