There seems to be a bug in std.getopt.
D doc says:
"To set timeout to 5, use either of the following: --timeout=5,
--timeout 5, --t=5, --t 5, or ** -t5 **. Forms such as -t 5 and
-timeout=5 will be not accepted."
However
bool reverseOrder = false, helpFlag = false;
int colOrder = 1;
getopt(args, std.getopt.config.bundling, "reverse|r",
&reverseOrder, "column|c", &colOrder,"help|?", &helpFlag);
sets colOrder to -1 rather than to +1 when the commandline has
"-c1" as arg.
Funnily, when the arg is *illegally* "-c 1", the variable is
set correctly to +1.
Given:
int colOrder = 1;
...
Could it be that "-c 1" is ignored because it is in invalid and
the default colOrder value is used?
This is not an urgent issue because there is a very simple
workaround:
colorder = - colorder;
But I thought it should be mentioned anyway and, if not noticed
it can create troublesome situations.
Being at that, the official rule "-t 5" is not acceptable is
problematic because that form is pretty commonly used on unix
and even sometimes used in docs.

I've noticed this before when using getopt. It is low priority
and a documented limitation but it would be nice if "-t 5" worked.
