Does it actually need to be .*? Not \s+ or something?

The text in this region tends to be of the form:
"https://server/path" + "@" +

But I don't think it's always of that specific form.  I think we only really
care that the line starts with the key and ends with a git hash, and we don't
care so much about the specific format of what's in the middle.

Fair.

       if m:
         head = m.group(1)
         break
