Code:
for f in *; do
  awk 'NR!=7 && NR!=8' "$f" >"$f.tmp"
  mv "$f.tmp" "$f"
done

It would actually be easier in sed, but if you have weird hangups about anything which isn't awk ...

ls has no particular use here; it's the shell which expands wildcards, not ls.

NAME
soelim - interpret .so requests in groff input SYNOPSIS
soelim [ -Cv ] [ -Idir ] [ files... ] It is possible to have whitespace between the -I command line option and its parameter. DESCRIPTION
soelim reads files and replaces lines of the form .so file by the contents of file. It is useful if files included with so need to be preprocessed. Normally, soelim should be invoked with the -s option of groff. Note that there must be no whitespace between the leading dot and the two characters `s' and `o'. Otherwise, only groff interprets the .so request (and soelim ignores it). OPTIONS
-C Recognize .so even when followed by a character other than space or newline. -Idir This option may be used to specify a directory to search for files (both those on the command line and those named in .so lines). The current directory is always searched first. This option may be specified more than once, the directories will be searched in the order specified. No directory search is performed for files specified using an absolute path. -v Print the version number. SEE ALSO
