"0.000", trimming trailing non-zeros and adding back trailing zeros.
Fix both the original bug, which was caused by walking off the beginning
of the fractional part of the value and into the integer part, as well
as the new bug, by terminating the trailing zero stripping when the first
non-zero character is encountered. Also, correctly calculate the number
number of trailing zeros that should potentially be removed if the format
contains trailing text characters.
Bump PORTREVISION.
