DIFadd and 1.000

[Friedrich2]

At least within longtable (probably generally), DIFadd and Co. have problems with numbers with points used as decimal separator. (E.g. 1.000 or 1.0456) yielding

How does this happen?

I know that it could take a while to close this bug, so please mention it within the latexdiff manual. The same holds for this issue, since it does not seem to be an easy-to-fix issue and my issue was hard to find (at least for me). As I currently do not have the time to compile a minimal example, I will likely add an MWE later. Besides: Thanks for your great work!

Thanks for reporting but I have trouble understanding what exactly is the issue. The example suggests a dot is turned into a comma, but maybe this is just a typo, as off the top of my head I cannot imagine how this could have occurred. Otherwise, this change-highlighting looks fine, or what do you expect?
Could you clarify this? Thanks
