-
-Fixes bugs in the emacs 23.1.1 version of `shell-command-on-region'
-
-Normally display output (if any) in temp buffer `*Shell Command Output*';
-Prefix arg means replace the region with it. Return the exit code of
-COMMAND.
-
-To specify a coding system for converting non-ASCII characters in
-the input and output to the shell command, use
-\\[universal-coding-system-argument] before this command. By
-default, the input (from the current buffer) is encoded in the
-same coding system that will be used to save the file,
-`buffer-file-coding-system'. If the output is going to replace
-the region, then it is decoded from that same coding system.
-
-The noninteractive arguments are START, END, COMMAND,
-OUTPUT-BUFFER, REPLACE, ERROR-BUFFER, and DISPLAY-ERROR-BUFFER.
-Noninteractive callers can specify coding systems by binding
-`coding-system-for-read' and `coding-system-for-write'.
-
-If the command generates output, the output may be displayed
-in the echo area or in a buffer.
-If the output is short enough to display in the echo area
-\(determined by the variable `max-mini-window-height' if
-`resize-mini-windows' is non-nil), it is shown there. Otherwise
-it is displayed in the buffer `*Shell Command Output*'. The output
-is available in that buffer in both cases.
-
-If there is output and an error, a message about the error
-appears at the end of the output.
-
-If there is no output, or if output is inserted in the current buffer,
-then `*Shell Command Output*' is deleted.
-
-If the optional fourth argument OUTPUT-BUFFER is non-nil,
-that says to put the output in some other buffer.
-If OUTPUT-BUFFER is a buffer or buffer name, put the output there.
-If OUTPUT-BUFFER is not a buffer and not nil,
-insert output in the current buffer.
-In either case, the output is inserted after point (leaving mark after it).
-
-If REPLACE, the optional fifth argument, is non-nil, that means insert
-the output in place of text from START to END, putting point and mark
-around it.
-
-If optional sixth argument ERROR-BUFFER is non-nil, it is a buffer
-or buffer name to which to direct the command's standard error output.
-If it is nil, error output is mingled with regular output.
-If DISPLAY-ERROR-BUFFER is non-nil, display the error buffer if there
-were any errors. (This is always t, interactively.)
-In an interactive call, the variable `shell-command-default-error-buffer'

+Fixes bugs in the emacs 23.1.1 version of `shell-command-on-region'
+
+Normally display output (if any) in temp buffer `*Shell Command Output*';
+Prefix arg means replace the region with it. Return the exit code of
+COMMAND.
+
+To specify a coding system for converting non-ASCII characters in
+the input and output to the shell command, use
+\\[universal-coding-system-argument] before this command. By
+default, the input (from the current buffer) is encoded in the
+same coding system that will be used to save the file,
+`buffer-file-coding-system'. If the output is going to replace
+the region, then it is decoded from that same coding system.
+
+The noninteractive arguments are START, END, COMMAND,
+OUTPUT-BUFFER, REPLACE, ERROR-BUFFER, and DISPLAY-ERROR-BUFFER.
+Noninteractive callers can specify coding systems by binding
+`coding-system-for-read' and `coding-system-for-write'.
+
+If the command generates output, the output may be displayed
+in the echo area or in a buffer.
+If the output is short enough to display in the echo area
+\(determined by the variable `max-mini-window-height' if
+`resize-mini-windows' is non-nil), it is shown there. Otherwise
+it is displayed in the buffer `*Shell Command Output*'. The output
+is available in that buffer in both cases.
+
+If there is output and an error, a message about the error
+appears at the end of the output.
+
+If there is no output, or if output is inserted in the current buffer,
+then `*Shell Command Output*' is deleted.
+
+If the optional fourth argument OUTPUT-BUFFER is non-nil,
+that says to put the output in some other buffer.
+If OUTPUT-BUFFER is a buffer or buffer name, put the output there.
+If OUTPUT-BUFFER is not a buffer and not nil,
+insert output in the current buffer.
+In either case, the output is inserted after point (leaving mark after it).
+
+If REPLACE, the optional fifth argument, is non-nil, that means insert
+the output in place of text from START to END, putting point and mark
+around it.
+
+If optional sixth argument ERROR-BUFFER is non-nil, it is a buffer
+or buffer name to which to direct the command's standard error output.
+If it is nil, error output is mingled with regular output.
+If DISPLAY-ERROR-BUFFER is non-nil, display the error buffer if there
+were any errors. (This is always t, interactively.)
+In an interactive call, the variable `shell-command-default-error-buffer'
+specifies the value of ERROR-BUFFER."
