[BUG] MSDeploy's skip is buggy when used with filePath AND skipAction

After looking at silverbyte's question, I decided to run some tests on skipping filePaths and I think I've found a bug. It seems that when skipping objectName=filePath AND skipAction=Delete, the file is deleted anyway. Performing the same statement with dirPath (and filtering on the containing folder), it works just fine.

I've also discovered that using skipAction=Delete but omitting AbsolutePath produces weird results (like only skipping files in the root directory), but I decided to leave that out since its behavior is undefined.

Below is a batch script which reproduces the problem (don't worry, it's safe. Just run it in an empty directory): 

@ECHO OFF

if /I "%%h" == "InstallPath" (
if /I "%%i" == "REG_SZ" (
if not "%%j" == "" (
if "%%~dpj" == "%%j" (
set MSDEPLOY="%%j\msdeploy"
)))))
