Remove non-breaking space at the beggining of comments

[Pierre-Sassoulas]

Black apply a space after a # in comment like so:

- #Comment content 
+ # Comment content 

The thing is, often we developers fat fingers an insecable space after creating the # by not releasing the Alt Gr key fast enough.

Then black had a space before it resulting in visually two spaces:

- # Comment content 
+ #  Comment content 

I'd like black to remove insecable spaces at the beginning of comment and then replaces them with a real space:

- # Comment content 
+ # Comment content

By "insecable space" do you mean the non-breaking space (nbsp) character https://www.compart.com/en/unicode/U+00A0 ? If so it seems reasonable to me for Black to replace leading nbsps in comments.

Yes, sorry if it was not clear I translated the name from french.

I'm interested to work on this, if a pull request with this change is going to be merged.

[JelleZijlstra]

I'd merge it (unless someone else comes up with a problem with this suggestion).

I made an attempt, but I have a crash with type ignore comment for python 3.6 and 3.7 and I don't quite know what to do with it. Do you have an advise on how to debug it ?
