groff_mm(7): Recast description of .AS.
* Use more descriptive metasyntactic variable names for parameters.
* Generalize; collected abstract "text" could conceivably include
drawing commands (or embedded EPS).
* Drop caveat about mixture of .COVER and .MT; this is now diagnosed.
* Describe what the indentation argument actually _does_.
* Document indentation defaults (scaling unit and value).
