Re: [PATCH 2/4] apply: apply works outside a repository

Björn Gustavsson [off-list ref] writes:

The documentation for 'git apply' talks about applying a
patch/diff to the index and to the working tree, which seems
to imply that it will not work outside a git repository.

Thanks.  I think the headline should also be reworded.  It currently
reads:

    Apply a patch on a git index file and/or a working tree

but historically and still in real life practices, when you use apply (as
opposed to am), you apply primarily to the files and optionally to the
index, so this should read something like:

    Apply a patch to files and/or to the index

We could say "to files in the work tree", but that would give a wrong
impression that the files we talk about must be in a directory that is
part of the work tree of some repository, so it probably is better without
it.

The same comment applies to the beginning of the DESCRIPTION section.  I
actually think your added text should reword the current two-liner there,
instead of being added at the bottom.  Here is my attempt.

    Reads supplied diff output (iow "a patch"), and applies it to files.
    With --index (--cache) options, the patch is also (only) applied to
    the index respectively.  Without these options, the command applies
    the patch only to files, and does not require them to be in a git
    repository.
