IMHO, we should wait until the patch is merged upstream and then fetchpatch it.

@cole-h it has been applied on master now.

not sure how to use fetchpatch though, esp that the master version is slightly different than 3.1b - the patch needs some slight adjustments (to not be rejected), which has been done in this one

ofc we can also wait until a new stable version is released, then this patch is going to be irrelevant :)

it normalizes the patch compared to fetchurl to better apply.

breaking tmux with bugs will hit a lot of people. Just being careful when fetching pre release patches.

Not sure how to respond :)

If everyone prefers to wait (maybe it's already released and can be upgraded cleanly? - I haven't checked), I'm happy for this pr to be simply closed :)
