Cleaning up output from the pager

[BrainMaestro]

For the pager (less), we use the option --no-init which is used by git as well. It causes the output to remain on the terminal instead of being cleaned up like typical less would do. I actually do not like this behavior and would prefer to remove it. Is there a reason it should be kept? Thoughts?

[BrainMaestro]

To remove that flag, we would also need to remove --quit-if-one-screen for short files to work correctly which might not be worth it. Reopen this if you feel differently

Really? It seems to work for me..

[BrainMaestro]

Short files like Cargo.toml work if you remove --no-init?

Yes, it seems to work, but I'm not sure if I'm missing something:

(the output is directly shown, no paging mode)

[BrainMaestro]

Hmm, might be a difference with GNU less in linux and the old BSD one in macOS. Guess we should just ignore this then

[dufferzafar]

@BrainMaestro I too want to have the pager clear its output upon quitting.

Is there a way I can go about configuring this for myself?

[BrainMaestro]

@dufferzafar not that I know of, but if #158 is implemented, then it should be easy to do
