In fact the @ expression was not allowed to be quoted, since the quoted
string was kept intact for a later call to glob(3).  Unfortunately, the
insert_file function, which handles reading the DOS file given as @
parameter doesn't handle quoting either.

I applied a patch which allows a simple, quoted string after the @
expression now.  So this works:

  @"a b\foo"

But this still won't work:

  "@a b\foo"

The @ must be the first character in a word.


Hope that helps,
Corinna
