Severity: wishlist
Recent versions of MS-Excel and also LibreOffice's Calc have a feature
that I find very useful: the ability of remove duplicate lines from a
given list (range). I think it would be worth to add such a feature
to Emacs.
That is: provide a function `delete-duplicate-lines' (or some such)
that removes all duplicate lines in the active region and prints in
the echo area a message like "Duplicate lines removed: <n>".
TIA.
PS: There has been some discussion about this in this thread:
http://lists.gnu.org/archive/html/help-gnu-emacs/2012-11/msg00417.html.
Jambunathan K provided a possible implementation, but it lacks the
message in the echo area (which I think is important).
