----
--- Passes selected or all buffer text to string shell command *cmd* as standard
--- input (stdin) and replaces the input text with the command's standard output
--- (stdout).
--- Standard input is as follows:
---
--- 1. If text is selected and spans multiple lines, all text on the lines
--- containing the selection is used. However, if the end of the selection is at
--- the beginning of a line, only the EOL (end of line) characters from the
--- previous line are included as input. The rest of the line is excluded.
--- 2. If text is selected and spans a single line, only the selected text is
--- used.
--- 3. If no text is selected, the entire buffer is used.
--- @param cmd The Linux, BSD, Mac OSX, or Windows shell command to filter text
---   through.
--- @name filter_through
