Subject: Change sys.exit to raise ImportError (#2440)
X-Git-Url: https://git.madduck.net/etc/vim.git/commitdiff_plain/0969ca4a46c4a2081be38f7e96a81a74b308c75f?hp=0969ca4a46c4a2081be38f7e96a81a74b308c75f

Change sys.exit to raise ImportError (#2440)

The fix for #1688 in #1761 breaks help("modules") introspection and also leads
to unhappy results when inadvertently importing blackd from Python. Basically
the sys.exit(-1) causes the whole Python REPL to exit -- not great to suffice.

Commit history before merge:

* Change sys.exit to Raise.
* Add #2440 to changelog.
* Fix lint error from prettier
* Remove exception chain for more helpful user message.
