Bug description

Great to see there are people willing to improve ocamlbuild !

So here are a few things:

1. The following _tags file works:

true : package(gg),
package(vg)

2. But not the following one:

true :
package(gg), package(vg)

3. Neither the following one:

true
: package(gg), package(vg)

Could we

a)
Either be more consistant in the \ treatement or even better, avoid it altogether (I don't know if it would render the grammar ambiguous)

b)
Have a gnu-style error messages (http://www.gnu.org/prep/standards/standards.html#Errors)
so that we can easily jump to the location of the error from our editors. This is what is currently reported:

Lexical analysis error: _tags: Bad key in configuration line at line 1 (from file: "_tags")
