Long doc strings show up garbled with --help about gflags HOT 7 CLOSED

I replaced the implementation of method DescribeOneFlag() in file 
gflags_reporting.cc in gflags-1.6 with that in gflags-1.2 and the issue was 
fixed.

The version of DescribeOneFlag() in gflags-1.5 is also good. So the bug seems 
to have been introduced in gflags-1.6.

The problem is in InternalStringPrintf in util.h. The second call to 
output->append() takes 'space' as the first argument. Instead, needs to take 
'buf' as the first argument.

Thanks for tracking this down!  I'll get a fix checked in.

Fixed in r59
