When using the option "Prune tracking branches no longer present on remote(s)", the result of the "Fetch" command yields the following git command to be executed:
"git -c diff.mnemonicprefix=false -c core.quotepath=false fetch --prune origin"

Please consider adding the ability to prune tags that are no longer present as well, using this command instead:
"git -c diff.mnemonicprefix=false -c core.quotepath=false fetch --prune --tags origin".
