 ==========================
 
 At the lexical level, a command comprises a sequence of words separated
-by spaces or tabs.  So these are all equivalent:
+by whitespace characters.  Note that newlines are treated as word
+separators and do *not* end a command or allow multiple commands to
+be done together.  So these are all equivalent:
 
 nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
 				<debugfs>/dynamic_debug/control
 nullarbor:~ # echo -c '  file   svcsock.c     line  1603 +p  ' >

-Command submissions are bounded by a write() system call.
-Multiple commands can be written together, separated by ';' or '\n'.
+Commands are bounded by a write() system call.  If you want to do
+multiple commands you need to do a separate "echo" for each, like:
 
-  ~# echo "func pnpacpi_get_resources +p; func pnp_assign_mem +p" \
-     > <debugfs>/dynamic_debug/control
+nullarbor:~ # echo 'file svcsock.c line 1603 +p' > /proc/dprintk ;\
+> echo 'file svcsock.c line 1563 +p' > /proc/dprintk
 
-If your query set is big, you can batch them too:
+or even like:
 
-  ~# cat query-batch-file > <debugfs>/dynamic_debug/control
+nullarbor:~ # (
+> echo 'file svcsock.c line 1603 +p' ;\
