I got a panic while running issue -a.

This line failed to print the error message https://github.com/rsc/github/blob/master/issue/acme.go#L70. I eventually figured I had to add

plumb to githubissue

to ~/lib/plumbing but that's not in the documentation. The panic trace is similar to the below (similar because line number is influenced by some print's I've added).

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x230 pc=0x7b6509]

goroutine 21 [running]:

issue: fix nil pointer dereference on plumb error
62d3705 
plumbserve() fails with a nil pointer dereferrence when it tries to
print errors via w.Err(). This happens because w is a dummy window
with a nil *acme.Win. This commit  replaces w.Err() calls in
plumbserve() with log.Printf(). It also extracts the plumbserve()
method out of *awin, given that the previous change removes this
dependency.

Fixes issue rsc#5.

plumbserve() fails with a nil pointer dereference when it tries to
print errors via w.Err(). This happens because w is a dummy window
with a nil *acme.Win. This commit  replaces w.Err() calls in
plumbserve() with acme.Errf(). It also extracts the plumbserve()
method out of *awin, given that the previous change removes this
dependency.

Fixes issue rsc#5.
