[PATCH v3 1/2] Allow using stdin in run_on_* functions

["Kevin Lyles via GitGitGadget" <gitgitgadget@gmail.com>]

From: Kevin Lyles <klyles@epic.com>

The 'run_on_sparse' and 'run_on_all' functions previously did not work
correctly for commands accepting standard input. This also indirectly
affected 'test_all_match' and 'test_sparse_match'.

Now, we accept standard input and will send it to each command that we
run. This does not impact using the functions for commands that don't
need standard input.
