The "short" format was added to "git status" recently to provide a less verbose way of looking at the same information. This has two practical uses:
1. Users who want a more dense display of the information.
2. Scripts which want to parse the information and need a
stable, easy-to-parse interface.For now, the "--short" format covers both of those uses. However, as time goes on, users of (1) may want additional format tweaks, or for "git status" to change its behavior based on configuration variables. Those wishes will be at odds with (2), which wants to stability for scripts.
This patch introduces a separate --porcelain option early to avoid problems later on. Right now the --short and --porcelain outputs are identical. However, as time goes on, we will have the freedom to customize --short for human consumption while keeping --porcelain stable.
Signed-off-by: Jeff King <peff@peff.net> --- No tests. Does this really need them? At this point, it would be pure duplication of the --short tests; I am inclined to leave such tests until later when there is actually a difference between the two formats (and then we will know _what_ to test).
