I named a bug report "[LBSE] Add 'viewBox' support" (webkit.org/b/241762) and used git-webkit pr to create a PR, which was only named "[LBSE] Add '" (https://github.com/WebKit/WebKit/pull/1622). There's a bug related to hyphens, I'll move on and fix the PR name but this might be relevant for others, so I'll open a ticket.
I think that you meant apostrophe, not hyphen - is that right?
This isn't about hyphens or apostrophes, it's about multiple commits in a PR. git-webkit is trying to craft a title that applies to all the commits in the PR (unsuccessfully, in this case). Basically, all those commits share "[LBSE] Add", so that's what we're titling the PR. We can definitely improve how we name multi-commit PRs, although it's not obvious exactly what the title of a multi-commit PR should be, especially when commits have as diverse headers as the commits in this PR.
