[PATCH 22/23] man/manlinks.sed: Drop unnecessary code.

[G. Branden Robinson]

It is no longer necessary to sift the "SYNOPSIS" section to find
additional topics for which we should generate links (or stub 'so'
pages) to the main page.

Tested by:
$ cat man/*.{1,1m,3x,5,7} | sed -f man/manlinks.sed > BEFORE
[apply this patch]
$ cat man/*.{1,1m,3x,5,7} | sed -f man/manlinks.sed > AFTER
$ cmp BEFORE AFTER && echo SAME
SAME
