    Hi,

`llvm-cov show` appears to use hard-coded permissions 0770 for output directories and 0666 for output files. For the HTML report, this means that `index.html` is world readable, but the additional HTML files for individual source files in the `coverage/` subdirectory are not. In our case, a build, which produced coverage data and invoked `llvm-cov show`, ran as root in a Docker container, and the non-root CI system could only collect a part of the report, not all of it.

This can of course easily be worked around by invoking `chmod`, but perhaps it would make sense for `llvm-cov show` to produce better permissions by default. Since it makes the files world readable already, could it do the same for directories? Or could it respect the environment umask?
