The --quiet option to dfind doesn't supress log output

[jprorama]

Running dfind --quiet doesn't appear to suppress logging lines as intended. The telemetry data still gets printed to standard output. Therefore capturing output from via the --print predicate includes but the matching entries and the log lines that show progress of dfind.

For example a run like the follwing

srun --mem 8G -n 1 -N 1 mpiexec -n 1 dfind -i data/newlines-dfind.dat --quiet  --print

Will include the following to log lines at the start of the output

[2025-07-22T18:39:10] Reading from input file: data/newlines-dfind.dat
[2025-07-22T18:39:10] Read 5 files in 0.004 seconds (1309.568 files/sec)

The source suggests these lines are MFU_LOG_INFO level and should be suppressed by --quite:

$ grep -r MFU_LOG_INFO src/*| egrep 'Reading from input|Read .* files in'
src/common/mfu_flist_io.c:        MFU_LOG(MFU_LOG_INFO, "Reading from input file: %s", name);
src/common/mfu_flist_io.c:        MFU_LOG(MFU_LOG_INFO, "Read %lu files in %.3lf seconds (%.3lf files/sec)",

The macro MFU_LOG(level, ...) should be skipping these logs because quiet sets mfu_debug_level = MFU_LOG_NONE in dfind.c

mfu_debug_level = MFU_LOG_NONE;
