[Bug preprocessor/31182] New: preprocessor doubles up digits in token pasting

[dsb at boyski dot com]

Very simple test case:

% cat /tmp/ff.s
#define Concat(a,b)     a##b
Concat(foo,2.2)

% cpp -P /tmp/ff.s
foo22.2

Notice that what should be "2.2" becomes "22.2". Also note that this occurs
while preprocessing assembler (-x assembler-with-cpp) code.
