[Bug-indent] indent-2.2.8: parsing bug

[Nelson H. F. Beebe]

In indent-2.2.8 (and the earlier 2.2.6 and 2.2.7 releases) on several
platforms, this simple test file (reduced from a much larger program)
uncovers an indent parsing bug:

% cat bug.c
#define FP(x) x

void 
foo(void)
{
    double dmax;

    if (3 < 10)
        dmax = (double)3 * FP(10.0);
    else if (3 < 30)
        dmax = (double)3 * FP(5.0);
}

Here is what happens:

% indent < bug.c
#define FP(x) x

void
foo(void)
{
    double dmax;

    if (3 < 10)
        dmax = (double)3 *FP(10.0);
indent: Standard input:10: Error:Unmatched 'else'
    else
if (3 < 30)
    dmax = (double)3 *FP(5.0);
}

If I change FP(10.0) to 10.0 in line 10, the error message does not
appear, and the output is correct.
