Log of console interaction

With a fresh Msys2 installation, pacman fails to run, because it keeps
producing "key lookup failed" errors. The user is prompted to with the
following message:

error: mingw32: key "5F944B027F7FE2091985AA2EFA11531AA0AA7F57" is unknown
:: Import PGP key 5F944B027F7FE2091985AA2EFA11531AA0AA7F57? [Y/n] Y

However, if the user selects "yes", pacman simply asks the same question again
after a short delay, in an infinite loop.
