Major bugsquashing with respect to -offset and -width:

1. Support specifying the .Bd and .Bl -offset as a macro default width;
while here, simplify the code handling the same for .Bl -width.
2. Correct handling of .Bl -offset arguments:  unlike .Bd -offset, the
arguments "left", "indent", and "indent-two" have no special meaning.
3. Fix the scaling of string length -offset and -width arguments in -Thtml.
Triggered by an incomplete documentation patch from bentley@.
