I'm not sure if this is a bug or something due to the way my editor is setup.

First of all, my editor is setup to use tabs instead of spaces.

What happens is I select and copy multiple lines, where the first line is indented with a tab.
I do not however, select that tab.

Then, I click at the end of another indented line in my script and press enter.
The cursor is now on a blank, indented line. When I paste, that indent is turned into all spaces.

Please let me know if there is anything unclear in the manual, in its part related to the editor settings. Then I'll try to clarify.
