Request: move cursor when commenting and uncommenting

[AndydeCleyre]

It would be nice if the cursor would move n spaces to the right upon commenting a line, and n spaces to the left upon uncommenting a line, where n is the number of characters in the comment style preceding %s. For example:

Comment Style	n
// %s	3
-- %s	3
# %s	2
<!-- %s -->	5

This only makes sense for single-line commenting operations.
