54545: A few very minor things coverity complained about

Coverity CID 1692322 in Src/glob.c:
  i'm pretty sure this is a false positive so add a debug message just in case

Coverity CID 1500752 in Src/Zle/compresult.c:
  remove unused assignment that also reads uninitialized pointer p

And two that were just near other things it complained about

Src/utils.c:
  Warn if maildir disappeared from under us

Src/Modules/system.c:
  stray \n in zwarn message

Src/subst.c:
  Use DIGBUFSIZE for buf holding digits

  This one would be a little hard to overflow in practice, you'd need a
  parameter at least 100000000000000 characters long, which is 100TB.
