Spaces in diff hunks incorrectly rendered

[Jun Omae]

I noticed that spaces in diff hunks are incorrectly rendered in #13764.

Two spaces between os._exit(0) and # exit ... are rendered like single space (checked with Firefox, Google Chrome).

Proposed changes in [8de52d27d/jomae.git]. We could use white-space: preserve-spaces and remove replacing spaces with  s.

Also, according to trac.mimeview.patch, similar rendering diff hunks exists in both trac.mimeview.patch and trac.versioncontrol.diff. I'll try to share/remove duplicated code.

    # FIXME: This function should probably share more code with the
    #        trac.versioncontrol.diff module
