Fix Travis test for pyc files in egg-info

[pganssle]

This fixes the issue that prevented the initial 40.6.0 release.

The problem is that ! is a special character in YAML syntax.

It'd be nice not to have to do the test twice. Would it be sufficient to do it in just one place?

[jaraco]

Regardless, getting the release out is the most important thing.

Yes, we should only keep the test in the install script.

@jaraco I don't think it actually happens twice in a single build, does it? I think the deploy hook runs separately from the test, so we're just doing this test both as part of the tests and as part of the deployment.

We can probably create a script that wraps bootstrap.py that checks for pyc files in the egg-info, or we can modify bootstrap.py like so:

diff --git a/bootstrap.py b/bootstrap.py
index 8c7d7fc3..61f8ae46 100644
--- a/bootstrap.py
+++ b/bootstrap.py
@@ -59,6 +59,10 @@ def run_egg_info():
 def main():
     ensure_egg_info()
     run_egg_info()
+    with open(os.path.join('setuptools.egg-info', 'SOURCES.txt')) as f:
+        assert not any(x.endswith('.pyc')
+                       for x in map(str.strip, f.readlines()))
+

I suppose it's fine to assume that if there are no pyc files in the version created by the deploy step, but they are built in different environments, and I don't think it hurts anything to make this particular assertion.

I'm merging, we can figure out the details so I can cut the release, we can figure out the details of how to do the test later.
