Re: [PATCH v9] Support auto-merge for meld to follow the vim-diff behavior

You cannot interpret an empty output from "git config section.variable"; it could be "[section] variable" (which is true), or it could be a sign that there is no "[section] variable = value" in the configuration (which you treat as false).

Catching common spellings of 'true' and 'false' in the output of the string version of "git config", while checking for 'auto' at the same time, may not be too bad as an optimization to save an extra call to "git config --bool 2>/dev/null" (and ignoring errors), so I am OK with that as long as you leave the empty output alone.
