Summary Fix a typo in the doc comment. Changes "effect" to "affect" in sentence describing future flushes. Related issue N/A (trivial comment typo fix) Guideline alignment One focused change in one file. No behavior or API changes. Validation Not run (comment-only change).

Right alignment of the last column only works when there is a trailing tab on the line. Otherwise the last column is left-aligned which looks strange. If this is a known restriction and not a bug it could possibly be documented.

Previously, a cell was a block of text to the left of some tab. This meant that a table like this: aa\tbb a\tb would be formatted as aa bb a b in right-alignment mode because the b's were not actually in a cell, and thus didn't get aligned. This commit modifies the notion of a "cell" in right- and center-alignment mode to also include text to the right of the last tab on the line. This text is now considered part of a cell and aligned accordingly. Implemented as describe above, this change would cause many trailing spaces to be printed in right- and center-alignment modes, including on empty lines. To alleviate this, trailing spaces in the final cell of a line are not printed. fixes #29
