[Rd] problem with parse(text=quote(name))

Calling parse(text=quote(name)) or text=as.name("name")
makes parse() prompt for input from the command line
and then it returns a parse of the initial characters
of 'name' (depending on how many characters were typed
at the prompt).   E.g.,

   > parse(text=quote(myName))
   > parse(text=quote(myName))
   > parse(text=quote(myName))

where the ? lines are where parse prompted for input
and I typed a valid R expression. 

I ran into this when starting to convert code that used
a deparse/parse cycle to avoid the cycle by storing the
expressions themselves and I hadn't yet taken out one
of the calls to parse(text=myText).

I see it in 2.10.1 and "R version 2.11.0 Under development
(unstable) (2010-03-07 r51225)."
