I just hit a 'BUG' in the builtin add -p, I'll try to write a reproducer later but
wanted to send a heads up now in case you can reproduced easily on your own with the below info.
Note that this is not new in 2.40-rc2, I'm still on 2.39.1.
Basically I have an unmerged path from a conflicted 'git checkout $branch -m'. I resolved
the conflict, but did not run 'git add'. And then I ran (in the 'doc' directory of the repository)
'git restore -S -p ../doc/path/to/file' and got:
```
BUG: add-patch.c:498: diff starts with unexpected line:
* Unmerged path doc/path/to/file
Aborted (core dumped)
```
and the backtrace from the core dump is the below:
```
Reading symbols from /home/me/bin/git...
[New LWP 4172500]
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `git restore -S -p path/to/file'.
Program terminated with signal SIGABRT, Aborted.
