Add option to show whitespace characters in diff

[andresovela]

Is your feature request related to a problem? Please describe.
It would be nice to be able to see whitespace characters in the diff panel. Sometimes I see stuff like this:

My IDE displays the whitespace characters like this:

Describe the solution you'd like
An option to enable displaying whitespace characters.

Describe alternatives you've considered
Maybe highlighting the parts of the line that changed could help.

this makes sense eventually but is not high on my priority list since I want/need to rewrite the whole diffing from scratch eventually to support external diff crates and not using the libgit2 internal one

@extrawurst Hi, truly an amazing project, and thank you for making it. I can click . for more options, type o for options, and then navigate to "Ignore whitespace" and change to true.

This works (!) thank you. But it only works for "Status [1]" view. But it does not work for "Log [2]" view after navigating to a commit.

I tried following https://github.com/extrawurst/gitui/blob/master/src/tabs/revlog.rs to find missing link of options. I see at

gitui/asyncgit/src/sync/commit_files.rs

Line 24 in 289eddd

get_compare_commits_diff(&repo, (id, other), None, None)?

the options are not passed, but I do not know about the codebase.

good catch but an entirely different topic. please feel free to create another issue (maybe we have one for it already?)

Och, this issue is to show and not ignore the whitespaces. My bad, sorry.
