Invalid escape sequence

[Gekiretsu]

Hello I've not submitted many issues before so I will try to be as thorough as possible in my explanation. I've used ranger for years as my primary file manager and just recently over the last few months I began to notice that anytime I am constantly receiving an error about a invalid escape sequence. I'm in school now and trying to teach myself python so I'm not sure at all how to fix this so any and all help I would be extremely grateful and appreciative. Below is the error that I receive every time I exit/quit ranger.

Hey @Gekiretsu it seems that this particular file is populated via the manjaro-ranger-settings package and not in this project. These seem to be compatibility issues w.r.t Python 3. Either way I ended up making the commit locally but the way to contribute to manjaro packages on a quick search seemed tedious - I'll just lay the diff right here in case u need it.

You should be able to apply this patch locally via patch -p0 < diff.patch where diff.patch is the patch above. The commit message I had for this added references as well

Pre-Patch:

$ ranger

/home/ophamster/.config/ranger/commands.py:29: SyntaxWarning: invalid escape sequence '\('
command="find -L . \( -path '*/\.*' -o -fstype 'dev' -o -fstype 'proc' \) -prune \

EDIT: I just noticed that that the errors that ur facing different from mine (the lines but the not the errors themselves) - so its more than likely that its coming from a different source - so I apologise for the confusion. But the fix remains the same and u should be able to apply the same method for ur case as well.
