You can customize `grep-highlight-matches' to the value `always'
if you are content with the problems it might cause like

I guess these escape sequences come from the grep switch --color that
outputs them around the matched strings. However, I can't reproduce your
problem. When I click on the file name that lacks of match highlighting,
it still visits the source file. What grep version do you have?
