Comment:

 I left some comments on the ticket:
 * document tor-coccinelle.h
 * document test_operator_cleanup
 * make try_parse.sh exit with a non-zero status if it finds any files
 * make (a mode for) try_parse.sh that shows the parsing errors, so they
 can be fixed
 * it looks like you missed some files:
 {{{
 $ find src/{app,config,core,feature,lib,test,tools,win32} -name *.c -o
 -name *.h | xargs ~/dev/tor/scripts/coccinelle/try_parse.sh
 # 143 files
 }}}
