>Description:

I would recommend adding a paragraph to   http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/slow-patch.html

which mentions that in order to get 'patch' to *not* prompt for file to patch, you should specify at least 3 or four lines of context for context or unified context diffs when diffing:

diff -C 4 foo.c.original foo.c > patch-foo.c
diff -U 4 foo.c.original foo.c >patch-foo.c
>How-To-Repeat:
Try to be a new porter and have this bite you!
>Fix:
Add paragraph:

In order to get patch to run non-interactively, you should create your patches with more lines of context than the default:

diff -C 4 foo.c.original foo.c > patch-foo.c
diff -U 4 foo.c.original foo.c >patch-foo.c
