RE: [sv-bc] query related with `timescale

That particular sentence refers specifically to the timeunit and
timeprecision declaration statements, not to the `timescale compiler
directive. Note that in that sentence, "timeunit" and "timeprecision"
are in Courier font and without spaces.

However, I think the testcase should still fail due to another
statement, "There shall be at most one time unit and one time precision
for any module, program, package, or interface definition or in any
compilation-unit scope." This refers to time unit and time precision
declarations in any way.
