Subject: [PATCH] coccinelle: grep Options and Requires fields more precisely
Currently, the required version for badzero.cocci is picked up from
its "Comments:" line since it contains the word "Requires".
Surprisingly, ld-version.sh can extract the version number from the
string "Requires Coccinelle version 1.0.0-rc20 or later", but this
expectation is fragile. Fix the .cocci file. I removed "-rc20"
because ld-version.sh cannot handle it.
Make the coccicheck script to see exact patterns for "Options:" and
"Requires:" in order to avoid accidental matching to what just happens
to appear in comment lines.
