    bin/sh               expand.c parser.c parser.h 
  Log:
  Fix expanding of quoted positional parameters in case patterns.
  
  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.
  
  Remove some white space at EOL.
  
  The sub-expression "(nulonly || 1)" always evaluates to true and
  according to CVS logs seems to be just a left-over from some
  debugging and introduced by accident.
  
  Remove collate_range_cmp() stabilization, it conflicts with ranges
  
  Replace various spellings with FALLTHROUGH which is lint()able
