[BZ#589366] Show whitespace differences in inline highlighting
Submitted by Oliver Gerlich
Link to original bug (#589366)
Description
It would be nice if the file diff view could (optionally) highlight trailing whitespace, so that users notice if they made a change that would introduce this. Some kind of "squiggly underline" or bold red text could be used for highlighting.
Personally, I use Meld for reviewing changes before committing, so it is the last stage where such mistakes could be caught. Some editors already show trailing whitespaces, but some don't; so I always check for trailing whitespace "manually" in the diff view, and it would be neat if Meld would help there.
