Heads up: LibreOffice Calc AutoCorrect will change characters when pasting multi-line text

If you paste multiple lines of text into a cell, Calc's AutoCorrect will change the first character of the last line to uppercase:

Copyfoo  =>  foo
bar      bar
baz      Baz

To fix this, go to Tools / AutoCorrect Options, choose the Options tab and uncheck every box. You're a programmer, you don't need wimpy AutoCorrect assistance.
