Fully implement the \B (validate numerical expression) and
partially implement the \w (measure text width) escape sequence
in a way that makes them usable in numerical expressions and in
conditional requests, similar to how \n (interpolate number register)
and \* (expand user-defined string) are implemented.
This lets mandoc(1) handle the baroque low-level roff code
found at the beginning of the ggrep(1) manual.
Thanks to pascal@ for the report.
