[PATCH] check: don't use multi-line coloring for the report

[Bert Wesarg]

less can't handle coloring which spans newlines because of performance
reasons. Thus, color each line of the check report by its own.

For reference, git had a similar problem and I talked to the less
maintainer about the problem. Here is the resulting fix in git:
