Standard gnupg folder created despite --homedir parameter

[Carola Grunwald]

Hello Werner,

many thanks for your involvement in this discussion.  GPG 2.1 took big
steps towards becoming a truly portable application.

May I ask how that translates into the Windows world?  Is it a way to
get rid of the ...\AppData\Roaming\gnupg folder?

I have all executables in my gpg main folder and call gpg.exe
exclusively from that directory with a '--homedir "...\gpg"' parameter,
while that gnupg folder still gets created.

Thanks
