Two issues caused groff/lintian warnings on the mdoc pages: 1. man/ruby.1: the MISC ENVIRONMENT list for RUBY_TCP_NO_FAST_FALLBACK opened a .Bl that was never closed before .Sh SEE ALSO, producing "A .Bl directive has no matching .El". 2. man/erb.1 and man/ruby.1: .Bl -tag -width "1234567890123" uses a long all-digit width string. Under groff 1.24 that is mishandled and floods "cannot adjust line; overset by ~5e7n" warnings, and mangled OPTIONS rendering. Replace it with -width "--encoding" (a representative tag). Verified with man --warnings: 0 warnings on erb.1/ruby.1/goruby.1 after this change (was 249 / 1399 / 0 on master).
