Broken exclusion counts in Scanner logs

Scenario

I have a project with 35 source files
I can choose to exclude four of those using sonar.exclusions, set at the project level via the UI.

Results

The way we're showing the number of source file exclusions at the scanner level differs between 6.7 and 7.9.
The 7.9 behaviour is also present in 8.1.

SonarQube 6.7, no exclusions:

INFO: Index files
INFO: 35 files indexed

SonarQube 6.7 with exclusions:

INFO: Index files
INFO: Excluded sources:
INFO: */.pli
INFO: 31 files indexed
INFO: 4 files ignored because of inclusion/exclusion patterns

SonarQube 7.9/8.1, no exclusions:

INFO: 35 files indexed
INFO: 0 files ignored because of scm ignore settings

SonarQube 7.9/8.1, with exclusions:

INFO: 31 files indexed
INFO: 0 files ignored because of inclusion/exclusion patterns
INFO: 0 files ignored because of scm ignore settings

4 files were ignored but we're just not telling users about it.
