Selecting by lines downward includes too many lines

[bronson]

Triple-click to select lines, and drag downward. The line following the selection is mistakenly included in the tabularization. Triple-clicking and dragging upwards works fine.

Same issue. I type into a new tab

test = 0
this is a long line

Then I triple click to select the first line. Then I run Tabularize over "=". This causes the '=' to be placed after the length of the second line, as if the second line had been included in the

It also happens with multiple lines. I type into a new buffer

test = 0
testing = 0
longest_testing = 0

Then I triple click and drag to select the first two lines. Then I run Tabularize over "=". Same a above, it runs as if the third line is also selected, and aligns the 3 '='s.
