Relative path output directory differs from full path for bash scripts coverage

[git-blame]

I'm doing code coverage for bash script with main script in X and helper scripts in Y. So my kcov options are --bash-dont-parse-binary-dir --bash-parse-files-in-dir=Y <output_dir> X/main.sh

If output_dir is a relative path (e.g., coverage, ../coverage) kcov will not find any coverage for helper scripts. If output_dir is absolute path (e.g., /tmp/coverage, `realpath coverage`), helper scripts have coverage information.

Have not tested to see if compiled code, etc. have the same problem.
