    bin/sh               expand.c parser.c parser.h 
  When parsing an invalid parameter expansion (eg. ${} or ${foo at bar}) do not
  issue a syntax error immediately but save the information that it is erroneous
  for later when the parameter expansion is actually done.  This means eg. "false
  && ${}" will not generate an error which seems to be required by POSIX.
  Include the invalid parameter expansion in the error message (sometimes
  abbreviated with ... because recovering it would require a lot of code).
