First result might be prefixed with "^[[?25h^[[0G^[[?25h^[[0G" in "older" Vim

[lencioni]

I'm not entirely sure when this started happening, but lately when I use :Ack, the first result was prefixed with ^[[?25h^[[0G^[[?25h^[[0G in the quickfix window. Obviously this prevents me from being able to press enter to open that result.

After updating Vim to include patches 1-1941, this problem seems to go away

[wincent]

Sounds like a fun one to bisect...

[lencioni]

Yeah, not even sure if it is worth digging into. Perhaps just having this information here will be enough to get future explorers unstuck.

[wincent]

Yeah, if I get any more reports I'll dig deeper. Otherwise will just leave this parked here for a while and write it off as an anomaly.

[wincent]

Closing this one due to inactivity.
