🐛 String mismatch encountered while superimposing style sections: ' ' vs 'E'

[joshtriplett]

I tried to run git grep -C10 ULT_MAN in the man-db git repository https://salsa.debian.org/debian/man-db.git, and got a panic:

thread 'main' panicked at 'String mismatch encountered while superimposing style sections: ' ' vs 'E'', /home/josh/.cargo/registry/src/github.com-1ecc6299db9ec823/git-delta-0.15.1/src/paint.rs:931:17

If I do git --no-pager grep --color=always -C1 ULT_MAN | delta I can reproduce the problem. However, if I redirect the output into a file, and then cat that file through delta, that doesn't reproduce the problem.

Thanks @joshtriplett!

I can reproduce this.

Ran into another "String mismatch" panic in the same repository, with git grep manpath; that one seems like it might be related to having a non-UTF-8 character on a line, as delta stops right before the line with that character (in it.po).

That would make sense, as I have git diff consistently making delta crash on our repo which has lots of ISO-8859-1 files. 😕

Thanks, we should fix this; should be a reasonably doable fix if anyone feels like looking into it. But if not I'll try to get to it soon and then make a release.
