Various pages: Add missing commas in SEE ALSO part II

This is a sequel to commit baf17bc4f2, addressing the
issues with missing commas in the middle of SEE ALSO lists that
emerged since.

The awk script from the original commit was not working and had to
be slightly modified (s/["]SEE ALSO["]/"?SEE ALSO/), otherwise it
works like a charm. Here's the fixed script and its output just
before this commit:

for f in man*/*; do
awk '
    /^.SH "?SEE ALSO/ {
	sa=1; print "== " FILENAME " =="; print; next
    }
    /^\.(PP|SH)/ {
	sa=0; no=0; next
    }
    /^\.BR/ {
	if (sa==1) {
	    print;
	    if (no == 1)
		print "Missing comma in " FILENAME " +" FNR-1; no=0
	}
    }
    /^\.BR .*)$/ {
	if (sa==1)
	    no=1;
	next
    }
    /\.\\"/ {next}
    /.*/ {
	if (sa==1) {
	    print; next
	}
    }
