git rev-parse has several options which print various paths. Some of these paths are printed relative to the current working directory, and some are absolute. Normally, this is not a problem, but there are times when one wants paths entirely in one format or another. This can be done trivially if the paths are canonical, but canonicalizing paths is not possible on some shell scripting environments which lack realpath(1) and also in Go, which lacks functions that properly canonicalize paths on Windows. To help out the scripter, let's provide an option which turns most of the paths printed by git rev-parse to be either relative to the current working directory or absolute and canonical. Document which options are affected and which are not so that users are not confused. This approach is cleaner and tidier than providing duplicates of existing options which are either relative or absolute. Note that if the user needs both forms, it is possible to pass an additional option in the middle of the command line which changes the behavior of subsequent operations.
