Update the selected text when commenting text

Is your feature request related to a problem? Please describe.

When commenting some text with the Format/comment menu item, a % character is inserted at the beginning of each line that is selected, at least partly. This is a "full line" logic. But after the change, the selected text does not follow this full line logic.

Describe the solution you'd like

Actually, If I select all the text, after I use the Format/comment menu item, the whole text is selected except the first character. That is not efficient.
What I would like: In next source

A B C

whatever I select in the first line, after using the Format/comment menu item, what should be selected is the whole line, including the heading % and the trailing EOL.

Of course, something similar should occur when more then one line are involved.

Thanks for reporting. In my patch, I didn't go "all in" as I didn't want to arbitrarily enlarge the user's selection (conceivably, it could just be that just a single character is selected in a very long line). I did amend the logic a bit though, as follows: if the selection starts at the beginning of a line, the "beginning of the line" property takes precedence, i.e., in that case, the selection is enlarged slightly to include the prefix and keep the "beginning of the line" property.
Please check if that works for you. Note that you can still modify the selection (i.e., hitting End (or Command+Right or whatever the Mac equivalent is) after commenting (or indenting, which uses the same code).
If it doesn't work for you, please convince me why I should mess with the user's selection (by potentially enlarging it dramatically), and possibly even create a selection when there was none to begin with (e.g., when there was only a cursor but no selection).
