it's confusing that remove dup lines has two meanings in different submenu.

[LennaHammer]

when using lines > remove dup lines, it works like the uniq command which keeps the first dup line,

but when using selections > sort lines > remove dup lines, the lines that appear twice will all be removed.

it's very confusing that the same command has two different meanings in two different submenus. I've used these commands incorrectly, I think it can be avoided by providing a better name.

@hpwamr : No it is no bug or regression, this is an option within the "Sort lines" working as designed.
@LennaHammer is correct, that the wording is not chosen well and may be misleading.

1. Remove unique lines. => OK
2. Remove empty lines. => OK
3. Remove white-space lines. => called in the Edit -> Lines -> menu: Remove Blank Lines - better: use same wording
4. Remove duplicate lines. => the meaning is as described by @LennaHammer : remove all duplicates (incl. first one) maybe we can find a better wording here.
5. Merge duplicate lines. => Merge duplicate lines (into the first one) - this is the same functionality as menu Edit -> Lines -> Remove Duplicate Lines - which removes all dupes except the first/original line.

So, functionality is correct - we should find better wording here - any suggestions ?
