At first, an OSC-8 URI range was added when we received the closing OSC-8 escape (i.e. with an empty URI). But, this meant that cursor movements while the OSC-8 escape was in effect wasn’t handled correctly, since we’d add a range that spanned the cursor movements. Attempts were made to handle this in the cursor movement functions, by closing and re-opening the URI. However, there are too many corner cases to make this a viable approach. Scrolling is one such example, line-wrapping another. This patch takes a different approach; emit, or update the URI range when we print to the grid. This models the intended behavior much more closely, where an active OSC-8 URI act like any other SGR attribute - it is applied to all cells printed to, but otherwise have no effect. To avoid killing performance, this is only done in the “generic” printer. This means OSC-8 open/close calls must now “switch” the ASCII printer. Note that the “fast” printer still needs to *erase* pre-existing OSC-8 URIs. Closes #816
