Regression, Renaming a "folder with dots" makes smartass-renaming choke

Try to rename a file/folder in explorer-filebrowser by pressing F2

If you rename a file in Windows XP, the explorer will always select the whole filename including the files extension.
If you rename a file in Windows 7, the explorer will only select the filename but without the extension. That is to protect your grandma from accidently changing the extension as well. Let's call this feature "smartass-renaming".

"smartass-renaming" was recently implemented in ReactOS as well and is the new default.

Observed result
Unfortunately "smartass-renaming" in ros also erroneously tries to exclude the extension when you try to rename a folder, which makes absolutely no sense
try it by pressing F2 over a folder called "LGeneral-1.4.4-win32"

0.4.14-RC-101-g065e47d_renaming_folder_multidots.log (nothing interesting)

Expected result
"smartass-renaming" should be limited to files, and should not get active when renaming folders
