🐛 Delta doesnt' show the entire diff

[CGamesPlay]

$ delta --version
delta 0.17.0
$ cat diff.patch  | delta

Delta doesn't show the full patch. It stops after line 972 "Install the project...". The "---" lines look suspicious, but such lines appear elsewhere in the file (search "Enabling feature profiling") and work just fine. Snippet of where delta stops showing output:

-[ 87%] No install step for 'wasmtime-crate'
-[100%] Completed 'wasmtime-crate'

I wonder if that has to do something with ANSI escape sequences occuring after the initial - a few lines below. Eg:

  ...

--- Installing: /home/runner/work/wasmtime/wasmtime/target/c-api-install/../c-api-install/lib/libwasmtime.a

It's much simpler, diff -u .. input starts with (in this case) --- /var/folder/... to describe the original filenames, but removing a line starting with -- (in this case -- Enabling feature profiling) creates a line that delta handles like a filename which results in garbled output.

Fixed in #1787
