Fix markup: bogus numerical arguments that were mapped to zero

silently (troff) or under protest (groff); table column width (also
fixed some .L arguments to match actual game output); spacing in
no-fill text; stray .FI, .in and .ce messing up indentation; stray .L;
misspelled request and escape names; escaping of control and escape
characters; properly ignore form-feed; argument quoting; extra
arguments to .NF.  Still broken: .L abused for headings, which
triggers many groff warnings about negative indentation.
