[PATCH 0/5] wt-status: fix an invalid memory read, clean up

Memory is accessed out-of-bounds when try to show --branch info in a repo with a detached HEAD. Add a test in patch 1 and a fix in patch 3, as well as some cleanups.

Rene Scharfe (5):
  t7060: add test for status --branch on a detached HEAD
  wt-status: exit early using goto in wt_shortstatus_print_tracking()
  wt-status: avoid building bogus branch name with detached HEAD
  wt-status: don't skip a magical number of characters blindly
  wt-status: use skip_prefix() to get rid of magic string length constants
