single_quote() over-writes the stack string, so just output the name
separately first.

 name in printalias")

I coulda swore I tested it and that's where I got my commit message from;
I try to always use my history verbatim for the messages,
for this exact reason.
That said, I can reproduce the bug on trunk and my clean original branch,
so dunno how that got there. my b.

On trunk:
  $ src/dash -c 'alias foo=bar "a|b|c"=d; alias'
  'bar'='bar'
  'd'='d'
With patch:
  $ src/dash -c 'alias foo=bar "a|b|c"=d; alias'
  'foo'='bar'
  'a|b|c'='d'
