The official documentation for gpgtar's "--directory" switch suggests that it should by default create a directory with the exact same name as the archive that is to extracted/decrypted to place the files in, but this is only partially true (at least on Windows anyways).
The way it works right now, it will take "foo.gpg" and create"foo_1_" instead of a plain "foo" directory.
The request, of course, is for modifying gpgtar's behavior so that "_1_" isn't added at all, either by default or alternatively through the use of a simple switch in case this "_1_" isn't an essential part of some standard that gpg may have been set up to comply to.
Thanks for your time and sorry for any inconveniences.
