Aha! Thank you! That "--" is a comment in Lua (that is commented line
that was removed in diff). First dash is from diff, next two came from
file itself.

Steps to reproduce the bug:

$ mkdir test
$ cd test
$ git init
Initialized empty Git repository in path/test/.git/
$ cat >file.ext
-- 1
-- 2
-- 3
-- 4
-- 5
^D
$ git add file.ext
$ git commit -m "one"
Created initial commit 9226cdf: one
 1 files changed, 5 insertions(+), 0 deletions(-)
 create mode 100644 file.ext
$ cat >file.ext
-- 1
-- 2
-- 33
-- 4
-- 5
$ git gui

And stage (sole) hunk. You see the error.

Hopefully the above steps would help to debug this bug directly. If
you still need any more info from me, please say, I'll be glad to
provide it.

Thank you again!
