Bug ID: 6875
Summary: "unknown exception" using `hg split` or `hg commit
--interactive`
Product: Mercurial
Version: 6.7.2
Hardware: PC
OS: Linux
Status: UNCONFIRMED
Severity: bug
Priority: wish
Component: Mercurial
Assignee: bugzi...@mercurial-scm.org
Reporter: err...@raelity.com
CC: mercurial-de...@mercurial-scm.org
Python Version: ---
This is on linux, working with a clone of a githug repo; probably developed on
windows.
Wondering if this could be a line ending issue.
To experiment, since `hg split` failed, tried `hg amend --extract; hg commit
-i`, same thing.
Entered command
```
$ hg split xscreen.cpp
```
`y` for the first hunk
then `e` for the second
```
record change 2/9 to 'xscreen.cpp'?
(enter ? for help) [Ynesfdaq?] e
```
When it brings up the editor, gvim, there is the message
```
"/tmp/hg-editor-xxx.diff" [CR missing][dos]53L, 1799B
File has 39 DOS-style endings out of 53 lines.
```
In the editor, there were only `+` lines. Deleted some of them,
wrote the file, exited the editor, crash.
```
