Unstack from pytest stack trace

[nedbat]

I have a pytest failure, it shows me a stack like this:

openedx_webhooks/tasks/github.py:61: in pull_request_changed
    current = current_support_state(pr)
openedx_webhooks/tasks/pr_tracking.py:160: in current_support_state
    current.jira_id = current.jira_mentioned_id = get_jira_issue_key(pr)
openedx_webhooks/info.py:214: in get_jira_issue_key
    for comment in get_bot_comments(prid):

Can vim-unstack learn to deal with that?

Hey Ned! sorry for not noticing this issue sooner; I'll take a look tonight.
