;-).
As there is no "inherent" type associated with each configuration variable (in other words, type of a particular configuration variable is something determined by the caller that wants the value of that variable), "git config list/get --type=auto" would not work, but it would not be too bad to allow "git config list --type=path" to treat everything as if it is a path and having to filter nonsense out of the result (like "core.bare = true/false" or even "core.bare" without value that means true, which may make the "*force* interpreting it as path" approach to barf), which is an inevitable consequence.

This one, however, I need to see the actual code before commenting, as I do not think key-value pairs have inherent types. The _only_ special case where you can tell what type the thing is is the valueless true, which we can safely say is inherently boolean. Everything else is text string, sometimes interpreted as boolean, sometimes number, sometimes human-scaled number, sometimes path (with possible tilde expansion), etc.
