Problem description: 
Test which includes line breaks added with the enter key result in an extra row for each line break when the text is copied and then pasted into excel

Steps to reproduce:
1. type 
1
2
3
4
 with a standard line break (added with just the enter key) between each numeral
2. select the text and copy

3. paste the text into an excel spreadsheet  

Current behavior:
Excel add an extra row between each of the numerals

Expected behavior:
Expect the text to be in contiguous cells 

Note:  While I accept that Excel may not meet standards for accepting pasted text, it does need noting that this behaviour only occurs with text copied from LibreOffice Text and some html.  I tried  Microsoft Word, Notepad and libreOffice spreadsheet and they function as expected.  
HTML from this website pastes oddly.  If the five lines from the libreoffice documentation page (https://www.libreoffice.org/get-help/documentation/) starting with LibreOffice 3.5 User Guides is copied there is an extra row inserted after the bolded heading line "LibreOffice 3.5 User Guides" and there are no extra rows added between the other four lines of text.  The source for this shows that the first line simply has the Strong attribute applied.  So, while I accept it is probably primarily M$ playing silly games with their excel paste functionality one needs to ask why is libreoffice copied text different to other?
