--check::
Instead of applying the patch, see if the patch is
- applicable to the current work tree and/or the index
+ applicable to the current working tree and/or the index
file and detects errors. Turns off "apply".
--index::
(which is the default when none of the options that
disables it is in effect), make sure the patch is
applicable to what the current index file records. If
- the file to be patched in the work tree is not
+ the file to be patched in the working tree is not
up-to-date, it is flagged as an error. This flag also
causes the index file to be updated.
