From: Eric Biggers <ebiggers@xxxxxxxxxx>
'_require_xfs_io_command set_encpolicy -s' does not work as expected
because the following in the output of 'xfs_io -c "help set_encpolicy"':
-s LOG2_DUSIZE -- log2 of data unit size
... does not match the regex:
"^ -s ([a-zA-Z_]+ )?--"
... because the 2 in the argument name LOG2_DUSIZE is not matched. Fix
the regex to support digits in the argument name.
