While we are discussing about diff, there is one thing that has been
bugging me occasionally, but the annoyance factor has not motivated me
enough to look into it myself, because I do not use it often:
--color-words. It appears that it shows lines that do not have any word
differences in bold (whatever diff.color.meta is configured) and I think
it should use plain color instead.
Was this intentional, or just a simple plain bug?
Plain bug. I even meant to implement your suggestion of having a variable
set of non-word characters, but never came around to work on it.
Hopefully this weekend...
I am not sure what that variable is about, but in the code you
have fn_out_diff_words_aux() that uses OLD/NEW/PLAIN and I do
not see where you try to color anything to METAINFO color.
Perhaps you are talking about a different problem? I am a bit
confused...
