Currently, if dmd -cov is invoked on an absolute pathname, e.g.,
/mnt/1/src/mysource.d, then when you run the program, it produces the coverage
report in a file named -mnt-1-src-mysource.d.

The use of '-' here as a substitute character for '/' is unfortunate, because
it interacts badly with Unix tools. E.g., you have to type:

    rm -- -mnt-1-src-mysource.d

instead of just:

    rm -mnt-1-src-mysource.d

because the initial '-' gets misinterpreted as an option.

Suggestion: use '_' instead of '-' as the substitute character.
