clean_coverage does not remove *.cov files from the julia directory

[jishnub]

generate_coverage writes out files in both the package src directory as well as the julia installation directory (in /share/julia/base). Running clean_coverage removes the *.cov files from the package, but not from the julia base directory.

I think it would be nicer not to generate these files at all, so I opened an issue for Pkg.

In case it helps others, this can also be achieved with the Unix find command. To list the coverage files recursively, starting from the current directory, one can use

find . -name "*.cov"

To remove all of the coverage files, the find command accepts an additional -delete option:

find . -name "*.cov" -delete
