   The best that I can tell, is it looks like the shell is grabbing the   
   "!-" sequence, and apparently leaving behind only the "!".  Try your   
   first approach, and let it fail, then using command history, review the   
   command.  Notice that it now says "... ' |perl -n -e 's/]+)>//;print;'   
         
      
   (press the "up" cursor key ...)   
      
      : elvira[syl] ~; echo '' |perl -n -e 's/]+)>//;print;'   
      
   If instead I escape the "!", it's handled as you intended:   
      
      : elvira[syl] ~; echo '' | perl -n -e 's/]+)>/<\!--   
   $1-->/;print;'   
         
      
   I hope that this helps.
