wt-status: consistently quote paths in "status --short" output

Tracked paths with SP in them were cquoted in "git status --short"
output, but untracked, ignored, and unmerged paths weren't.

The test was stolen from a patch to fix output for the 'untracked'
paths by brian m. carlson, with similar tests added for 'ignored'
ones.
