This patch limits the number of fractional digits used to calculate the
fractional component of editcap's -t and -w options.
Specifically this patch truncates the fractional component (if any) of the -t
and -w options to 6 and 9 respectively.
Without this patch in place, fractional digit sequences having leading zeros
and a strlen containing more than the expected number of digits results in
incorrect fractional digit values.
This problem was found when using editcap -t with a value of "0.0124035".
A workaround for this bug is to manually limit the number of fractional digits
presented if any leading zeros are present: e.g. -t 0.012403 instead of -t
0.0124035.
This patch probably should be ported over to next public release.
