Subject: Assert that the argument to Run is a sequence of strings
X-Git-Tag: v0.14~112
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/06104c208673fdfdbcc320d59e8fb9658330edc3?hp=f0de3f92cc85c3d5e1dd3511578b01e46652e93c

Assert that the argument to Run is a sequence of strings

This runtime assertion makes bugs easier to find.

In most other languages, we'd have been able to check this at compile
time. But this is Python. Yay!
