Tab completion adding spurious escape characters

[Steven Penny]

If you create this file:

    touch -- \''-#%.!$&(),;@[]^`{}=_~+9zZ'

Then enter "touch", "Tab", "Tab", you get this:

    touch \'-#%.\!\$\&\(\)\,\;\@\[\]\^\`\{\}\=_~+9zZ

So the shell is saying that these characters need to be escaped:

    ' ! $ & ( ) , ; @ [ ] ^ ` { } =

but they dont, not all of them:

    $ (set -x; true \' \! \$ \& \( \) \, \; \@ \[ \] \^ \` \{ \} \=)
    + true \' '!' '$' '&' '(' ')' , ';' @ '[' ']' '^' '`' '{' '}' =

Notice carefully that the shell removes escaping for these:

    , @ =

but tab completion is adding it. Is this an issue of Readline or Cygwin?
