 Yes, this is a known bug that has been fixed a while ago. I guess
 it is time to release 6.15.01:
 
   5. cd - twice from a directory that contained a glob pattern,
      expands the glob twice (Mark Santcroos)
   4. MidnightBsd support (Lucas Holt)
   3. Fix history substitution core-dump with no history entries
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   2. Merge two character tables that are the same (Martin Kraemer)
   1. On ancient 7 bit locales, punctuation characters are used to
      denote special characters such as umlaut, adiaresis, etc.
      These characters return true for isalpha/isalnum. Ignore them
      because they break parsing (Martin Kraemer)
