#37 markup for coverage getting confused

[Sven Beyer]

There are cases with 2 instrumented locations in a line where the markup does not match the results. If you instrument attached TCL and have it run through writing 1 file successfully, the log looks as epxected - the condition part of the if lines covered (the ,2 locations) and the actioan if part not.
Interestingly, when doing markup, the 3rd if branch is annotated as not covered, but the first 2 are annotated as covered (which I assume comes from the if condition being covered). Not sure why the 3rd if looks different in markup than the first 2 as the log seems identical fo the 3...
