Issue: --chdir switch with space in the path

[TinyVanessa]

I checked the issues previously reported and could not see what I am reporting. Also, I googled to find an explanation and could not find any relevant info.
I recently discovered gsudo.exe while looking for an alternative to NSudoLC.exe (archived), to run as system so I don't have to keep changing the access rights. I ran few tests to see how the switches behave before I use them, I discovered that the switch --chdir fails if the path has spaces.
I am looking for an explanation not a workaround, I can implement my own workarounds, including not using the tool.
Examples:
(1) OK = works
C:\Users\Public\Downloads>gsudo.exe -i system -s -d --chdir C:\Users\Default dir /b
Desktop
Documents
Downloads
Music
NTUSER.dat
Pictures
Videos
(2) ERROR = Fails (because of the spaces)
C:\Users\Public\Downloads>gsudo.exe -i system -s -d --chdir "C:\Program Files\Internet Explorer" dir /b
Error: Invalid directory: "C:\Program Files\Internet Explorer"
