BUG: gpgconf --apply-defaults seems to fail if it's in a directory with a space

[Adam Milazzo]

Looks like it's invoking the shell without quoting the program to run, 
or something like that:

C:\Program Files\GNU\GnuPG>gpgconf --apply-defaults
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
gpgconf: Option gpgconf-gpg.conf, needed by backend GnuPG, was not 
initialized
gpgconf: fatal error (exit status 1)
