from_clipboard doesn't work by default when copying string cells from excel #6223
Description
need to do pd.read_clipboard(sep='\t') and then things work fine.
Since it's for interactive use, it should be ok to change the default
without breaking existing code.
we did the same to to_clipboard() in #5070, I missed the fact that
read_clipboard only works out of the box for pure numerical data right now.
Why don't users report this stuff I don't know.
