Fix for line number prefixing on output using -me and tables

[G Helffrich]

Dear Groff Developers -

        Here is a bug report and patch to 1.21 groff to fix for the handling of 
line number prefixing on output (via the .nm request).  The fix is to the -me 
macros to work properly when .n1 and .n2 are used, and for the tbl preprocessor 
to handle numbered line output.  At present, neither produce the correct 
results.  I attach a test input file that shows the range of problems 
encountered, a PDF with the result of running groff 1.21 on this input, a patch 
that fixes the -me macros and tbl, and a PDF file with the result of running 
the patched groff on the same input file.
