show messages only for build exceptions

[adamralph]

Since each target is a one-liner which calls SimpleExec, the stack traces are useless. This changes this:

Thanks @adamralph! Since I merged your other PR, could you please rebase this one?

[blairconrad]

I very much like the effect, @adamralph. I'm glad you brought the PR though, since I find the new syntax to be a little opaque. But then again, where was I to comment when you were developing it?

[adamralph]

Rebased.

It's only a beta feature so I'm still open to suggestions. 😃

BTW - there is another overload which takes a IEnumerable<Type> for specifying an arbitrary number of exception types:

RunTargetsAndExit(args, exceptionMessageOnly: new[] { typeof(CommandException) });

It has the advantage of being able to write exceptionMessageOnly: which, come to think of it, could be reduced to messageOnly:. But as you can see it's quite verbose because of typeof and again, symbol-heavy because of the lack of a nice array initializer in C#. The <T>, <T1, T2>, <T1, T2, T3>, and <T1, T2, T3, T4> methods are just syntactic sugar over this method.

Thanks, @adamralph!

Thanks, @adamralph. I suppose if there was a one-type overload that took an exceptionMessageOnly, that would help a little. At least when there's only one type.
I'm trying to think of something else that could convey what's going on without being too wordy, but am so far coming up short. I'll be in touch if that changes!

Maybe a predicate parameter would make things clearer

[adamralph]

@thomaslevesque I assume you mean like this?

RunTargetsAndExit(args, messageOnly: ex => ex is CommandException);

I really like that! I'll sleep on it, but I think that may be a much better way to do it.
