SUMMARY

When a filename appears in the program output, it may be underlined and opened directly by control-clicking.

When the filename is followed by a :number or :number:number annotation, this usually signifies a line number or combination line number/colon number in compiler or text processor output.

However, even though konsole correctly adds the ':' suffix to the filename to be opened - ie. it should in fact pass the suffix to the program responsible for opening the file - it does not ignore the suffix when attempting to open the file at all, leading to a "the file or folder does not exist" error as it tries to open "filename:123" directly.

STEPS TO REPRODUCE
1. open konsole
2. in profile settings -> mouse -> miscellaneous, enable "underline links"
3. touch filename.txt
4. echo filename.txt
5. ctrl-click the filename.txt, observing that the file is opened
6. echo filename.txt:20
7. ctrl-click the filename.txt:20

OBSERVED RESULT

An error appears, indicating konsole is trying to open "filename.txt:20", a nonexistent file.

EXPECTED RESULT

filename.txt should open at line 20. That is, "filename.txt:20" should be passed to the app responsible for handling "filename.txt".
