[PATCH 4/9] scan_profile(): Make sure the buffers are initialized

[Tim Hentenaar]

Be sure to initialize the two char buffers in scan_profile().

This fixes a warning from valgrind about the conditional at
of BUFSIZ chars with automatic storage duration. This fixes a warning
from valgrind about the conditional on line 805 relying on uninitialized
data.
