Line ending with `{` is flipped to `}`

Easy 100% repro for me:

$ echo foo > cat
$ echo bar { > dog
$ cwdiff cat dog
foobar }

Looks like the color_filter is the culprit.

Ditto for [, which gets flipped to ].

$ echo "[ x ]" > foo
$ echo "x" > bar
$ cwdiff foo bar
]x ]

@lemzwerg I haven't used cwdiff for years, do you want to take it over?

[lemzwerg]

Alas, I'm swamped with work for LilyPond and FreeType, sorry.

Maybe I'll find some time to check #7, but I can't promise anything.

No worries, I remember that #7 failed on OSX back when, hence I didn't merge it, but I might need to try it again.
