This option is what you need to know about...  it's not specific to
completion, which just uses the normal command hash table.

HASH_EXECUTABLES_ONLY
       When  hashing  commands  because  of  HASH_CMDS,  check that the file to be
       hashed is actually an executable.  This option is unset by  default  as  if
       the  path  contains  a large number of commands, or consists of many remote
       files, the additional tests can take a  long  time.   Trial  and  error  is
       needed to show if this option is beneficial.
