For the underlying patch-tool described here:
https://github.com/google/verible#interactive-formatting

It would be nice if the diff could be colorized for readability. Currently it is monochrome.

Example mock-up using (github markdown's default coloring):

$ verible-verilog-format-changed-lines-interactive.sh 
--- /home/fangism/local/src/lowRISC/opentitan/hw/ip/aes/rtl/aes_core

Thank you for developing a great tool. I recently started to use this tool because I want to use the fixer feature. However, I realized there's no way to check diff without actually fixing my files. Could you consider adding diff feature so I can go ahead applying the changes without worries?
