-If you would like to split a single shell command into multiple lines of
-text, you must use a backslash at the end of all but the last subline.
-Such a sequence of lines is combined into a single line, by deleting the
-backslash-newline sequences, before passing it to the shell.  Thus, the
-following is equivalent to the preceding example:
+A shell command can be split into multiple lines of text by placing a
+backslash before each newline.  Such a sequence of lines is provided
+to the shell as a single command script.  The backslash and newline
+are preserved in the shell command.  If the first character on the
+line after a backslash-newline is a tab, the tab will @emph{not} be
+included in the shell command.  So, this makefile:
 
 @example
 @group
-foo : bar/lose
-        cd bar;  \
-        gobble lose > ../foo
