Subject: Add support for custom `task` location or command
X-Git-Url: https://git.madduck.net/etc/taskwarrior.git/commitdiff_plain/47ee2ff2a334a50137255faa54504594be9eaf6d?ds=inline

Add support for custom `task` location or command

Thanks @xarthurx for proposing WSL support in #62. This commit adds
support in a different way, by allowing the "task" command to be
customised (to `wsl task`, for example).
