Quoting problem when there are several targets

[ghost]

Problem exposed by the test added in #699

I suggest that we use the following model, that I find slightly simpler than the current one:

A variable always expand to a list of values. When a variable expands to exactly 1 value, there is no ambiguity and it can appear anywhere. When it expands to 0 or more than 2 values, it can appear:

• either inside a quoted string, in which case it expands to the list of values concatenated by spaces
• either as a whole atom inside a variadic functions, in which case it expands to one argument per value

I'll try to have a look later today (in the evening CET).

I'm afraid it'll have to wait for tomorrow.

@Chris00 do you think you'll have some time to look at this in the coming weeks? I'm thinking that it'd be nice to sort this out before we release Dune 1.0.0.

I agree. I'll try to find the time but there are a couple of things I definitely need to finish first...

@Chris00 I'll take over this if you don't mind. I'd like to have this fixed to support version comparisons.

@rgrinberg Thanks — I'm doing too many things ATM...

Fixed in master.
