Giving #1281 a go.
This PR allows certain environment variables to take precedence over config settings, while allowing them to be overridden by their respective command line flags.
It does this by formatting those variables as a vector of command line args, and then inserting them between the config variables and command line args in
App::matches(). Parsing the env variables in that way allows some env variable-specific code inAppto be removed as well.Right now, the env variables I picked are
BAT_TABS,BAT_THEME,BAT_PAGER, andBAT_STYLEas I think those make the most sense to replace. It is straightforward to add more if needed. Note thatBAT_PAGERtakes precedence over config variables, butPAGERdoes not.Also adds tests for the
cachesubcommand to make sure the changes don't break it (e.g. by inserting flags beforecache).Fixes #1152
