make .bat and .cmd files work for editors on windows

[pm100]

This Pull Request fixes/closes #1316

if command launch on windows fails then retry doing

cmd /C <editor> <file name>

verified that it fixed vim (original bug) plus code (added by commenter)

it is arguable that the rust core code should do this, they get close but are not quite there

I followed the checklist:

• I added unittests
• [x ] I ran make check without errors
• [ x] I tested the overall application
• I added an appropriate item to the changelog

Is there a way to add a test for this?

Is there a way to add a test for this?

Thanks for twisting my arm into doing that

• I found many odd quirks in my implementation. I hesitate to use the word 'bug' :-)
• I learned a huge amount about rust testing

Gonna pull the PR while I tweak
