The \c escape

[Colin Plumb]

I'd like to endorse this proposal.  It has practical value, it breaks
nothing, and is not terribly hard to implement.

This would also be useful in long character constants, where I don't
think string pasting is allowed.

I would prefer '\ ' to '\c', since a non-alphanumeric character better
indicates the magicness of the escape, and ' ' is as close to the
"nothing" meaning of the escape as printable ASCII can get.

Again, it is a useful, trivial change.  I shall certainly hack it
into the next C compiler I get.
