>Description:
Port ports-mgmt/portlint should determine correct usage of true/false and ${TRUE}/${FALSE}.

Issue is related to DESKTOP_ENTRIES: in case last parameter is set to true/false, portlint says:
possible direct use of command "false" found. use ${FALSE} instead.

But in case this is switched to ${TRUE}/${FALSE}, portlint says:
Use true/false instead of ${TRUE}/${FALSE} in DESKTOP_ENTRIES.

In case it is switched to $TRUE/$FALSE, portlint says:
looks fine.
>How-To-Repeat:
Take a port containing "DESKTOP_ENTRIES" and try the different versions of the last parameter as described above.
>Fix:
n/a
