At last, someone with a glimmer of sense!  \c *already* is a funny
kind of \.  Except with respect to whichever character indicates the
end of the quoted string.  This inconsistency is a *bug*.

For instance:

$foo = 'bar'; print "\c$foo";     yields 'dfoo', not an error
$foo = 'bar'; print "\c\$foo";    yields chr(28).'bar', not 'dfoo'

From this, "\c\" should yield chr(28).
And "\c"" should yield 'b', just as qq'\c"' does.

Alternatively, \c\ should always apply the \c 'operator' to the
following character, so that "\c\"" works like qq'\c"' (as it
currently does) but it takes \c\\ to get a chr(28).
