Case sensitivity for --filter

Currently, the matching of tests for --filter is case sensitive. It happens a lot to me that no tests are running at all, due to writing the filter all in lowercase rather than putting capital letters matching the test name.
Would it make sense to perform a case-insensitive match instead ?

Maybe. You can also pass a regular expression that works in a case insensitive way.

passing a regular expression is more complex. I still think that being case insensitive for the simple matching would make more sense.
