Is the case normalized in both of them, or does it need to be case
insensitive? Your two examples ("sort iu" vs. "s/^\(.*\n\)\1/.../")
conflict in how they handle case sensitivity. In either case, I'd be
tempted to use a "decorate/process/undecorate" pattern, performing
some transformation on each duplicated line. If case is the
significant, you could do something like
:set sw=4 ts=4 noet
:%sort i " sort like lines together
:g/^\(.*\n\)\1/s/^/XXX " mark duplicates
:v/^\t/d " delete the non-indented lines
:%s/^XXX " unmark the lines of interest
:sort iu " optionally remove duplicates if there
" were more than 2 duplicated entries
If you need case insensitivity, you can do something like this for
the 3rd command above:
:1,$-1g/^/if toupper(getline('.'))==toupper(getline(line('.')+1))|sil!> |endif
You just need something that is unique to the lines you want to save.
