largefiles: ensure addlargefiles() doesn't add a standin as a largefile An easy way to force this (and cause a traceback) prior to the fix for 3507 was $ touch large $ hg add --large large $ hg ci -m "add" $ hg remove large $ touch large $ hg addremove --config largefiles.patterns=**large This patch also detected (and corrected) a previous test where a standin got added as a largefile (without a traceback).
