uncovered option to display only less than 100% coverage

[KEINOS]

I would like to thank you in advance for providing us such a helpful and cool tool!!

I understand that 100% coverage is a myth though, I would like to have an option that only shows the uncovered ones, if possible.

 usage: go-carpet [options] [paths]
   -256colors
     	use more colors on 256-color terminal (indicate the level of coverage)
   -args string
     	pass additional arguments for go test
   -file string
     	comma-separated list of files to test (default: all)
   -func string
     	comma-separated functions list (default: all functions)
   -include-vendor
     	include vendor directories for show coverage (Godeps, vendor)
+  -mincov int
+     	only show files that coverage were less than this value (default: 100)
   -summary
     	only show summary for each file
   -version
     	get version

My current workaround is to create a shell script as below. But it would be nice to have it by default.

#!/bin/bash

name_file_coverage='coverage.out'

# getNameFilesUncovered echoes file names in comma-separated list which didn't
# cover 100%. This will be used for “go-carpet` -file option.
function getNameFilesUncovered() {
    list=$(go tool cover -func="$name_file_coverage" | grep -v '100.0%\|init\|total' | awk '{print $1}')
    echo "$list" | while IFS= read -r line; do
        basename "${line}" | sed -e 's/\.[^\.]*$/\.go/'
    done | uniq | tr '\n' ','
}

# Run test and create cover profile
go test -timeout 30s -cover -v -coverprofile "$name_file_coverage" ./...

# Run go-carpet by specifing files into test
go-carpet -file "$(getNameFilesUncovered)"
