[issue14803] Add -C option to run code at Python startup

[Ned Batchelder]

Ned Batchelder <ned at nedbatchelder.com> added the comment:

The difficulty that coverage faces is not measuring python programs started from the command line like this, you can use "coverage run myprog.py" or "python -m coverage run myprog.py".

The difficulty is when there are subprocesses running python programs.  Read http://nedbatchelder.com/code/coverage/subprocess.html for the two current hacks used to invoke coverage on subprocesses.  If -C is implemented, it should have a PYTHONRUNFIRST environment variable (or the like) to make these hacks unnecessary.
