When changinh the content of a file, the file manager view is not updated
to display the new file size (when displayed). The monitor actually
receives the file change event, but no update is made.

To reproduce, install FAM with (or without ?) imon kernel patch.
Then open View as Icons/List on a directory. Create an empty file in that
directory:
# touch aFile.txt
The file aFile.txt appears in the file manager. Then add some content in
the file. This should (will) triger the FAMChanged event for the file.
# echo "This is a test ..." >> aFile.txt
# echo "But nothing happens ?" >> aFile.txt
The icon/entry should update to reflect changes in the file content (size,
content preview, ...). If a directory is monitored and the change is the
creation of a file inside it, the number of elements is not updated.

It should be noted that:
-For files:
    when the icon/entry is selected or when Ctrl-R is pressed, infos,
content preview are correctly updated.
-For dirs:
    when the icon/entry is selected, # of elements are NOT updated. Ctrl-R
have to be hit to have displayed infos correctly updated.
