🐛 Syntax highlighting fails when the visible snippet includes a multiline comment

[j1ah0ng]

• [x] Please include the raw text output from git, so that we can reproduce the problem. (You can use git --no-pager to produce the raw text output.)
• [x] A screenshot of Delta's output is often helpful also.

It seems that in the case where the diff window happens to include the start of a multiline string (e.g. in this Python example ""') the rest of the output is treated as a comment. See the second block in the image:

Thanks for filing a Delta bug report!

This may be fixed by #1091

Hi @j1ah0ng, thanks for reminding me about #1091. I'm going to close this because it's a dup of #117, but I agree -- I have wanted this to be improved for a long time, and #1091 seems like a good suggestion.
