Warmup might display which files will be directly affected by conversion

[jurosh]

Now warmup only list all files which will be processed - they might be changed or not, depends on execution.

Would be nice to see which files will be really updated and which does not need modification because have correct line ending.

Also would be nice to add percentage of all files which needs to be modified.

Eg.

Files will not be touched (have proper EOL):
{LIST1}

Files will be updates (needs EOL conversion):
{LIST2}

XY% files needs to be updated.
