coccicheck: replace --very-quiet with --quiet when debugging
When debugging (using --profile or --show-trying) you want to avoid supressing output, use --quiet instead. While at it, extend documentation for SPFLAGS use. For instance one can use: $ export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci $ make coccicheck DEBUG_FILE="poo.err" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c Expand Documentation/coccinelle.txt as well. v4: expand Documentation/coccinelle.txt v3: rebased, resolve conflicts, expand Documentation/coccinelle.txt v2: use egrep instead of the *"=--option"* check, this doesn't work for disjunctions.

+You can use SPFLAGS to add debugging flags, for instance you may want to
+add both --profile --show-trying to SPFLAGS when debugging. For instance
+you may want to use:
+ rm -f err.log
+ export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci
+ make coccicheck DEBUG_FILE="err.log" MODE=report SPFLAGS="--profile --show-trying" M=./drivers/mfd/arizona-irq.c
+err.log will now have the profiling information, while stdout will
+provide some progress information as Coccinelle moves forward with
DEBUG_FILE support is only supported when using coccinelle >= 1.2.
