GCC Manual: awkward paragraph in RTL Classes and Formats

[Steve Christiansen <smc at us dot ibm dot com>]

There is a paragraph in RTL Classes and Formats that claims
there are four format characters and then describes five.
The paragraph is followed by a table which lists five more.
The following patch attempts to clarify.

Please apply if ok.  I have no write access.

Thanks

Steve

-expression (actually a pointer to an expression), @samp{i} for integer,
-@samp{w} for wide integer, @samp{s} for string, and @samp{E} for vector
-of expressions.  The sequence of letters for an expression code is

-@samp{ei}.
