This will allow to use reporters from matchers avoiding stupid direct
writes to $stderr.
Also it will allow to remove matching from CLI altogether in a phase of
the runner. Allowing to decouple Mutant::Config from VM environment
allowing to serialize it ;)
Step by step. Takes a while.
* I do not use 1.9.3
* Also keeping them in each file increases mental overhead (true it *can* be autoamted)
* None of the files encodes NON ASCII chars.
* I do not expect it makes any difference, since nobody programmatically
will consume strings generated by mutant under the assumption they are UTF-8 encoded.
* 1.9.3 Users have to deal with the encoding fuckup under ruby anyways.
This avoids situartions where the source contains (begin, other)
nodes that get mutated to (other) where there is no difference in the
source.
Closes#198
