[issue3202] largefiles does not remove empty directories when updating to different branch

[Paul]

New submission from Paul <mercurial at paulsweetman.com>:

largefiles extension bundled with Mercurial 2.0.2

If you're in a branch with a directory (let's say it's called "should_go") 
that contains only large files, and you update to a branch where that 
directory should not be present, the largefiles in the directory are 
correctly removed but the empty directory is left behind.

Here is a script to reproduce:

---------8x----------
hg init lftest
cd lftest
touch afile
hg add 
hg commit -m "add a file so we can commit"

hg branch testbranch
mkdir should_go
touch should_go/mylargefile
hg add --large should_go/mylargefile
hg commit -m "add largefile"

hg up default

ls -R  #The should_go dir should not be there, but it is
---------8x----------

If you run this script without the "--large" flag on the file being added 
then you can see vanilla Mercurial behaviour is different.
