Subject: [PATCH] Revert "small performance improvement for prepare_arrays() by
 replacing grep + awk by awk only"

This reverts commit 3b1638f60309b1c4e9636c6f5b62c71b22ff4cd1.

I'm not sure what went wrong here, but these commands are not equivalent.

$ export hexc=0x00,0x05 && openssl ciphers -tls2 -V 'ALL:COMPLEMENTOFALL:@STRENGTH' | grep -w "$hexc" -
          0x00,0x05 - RC4-SHA                 SSLv3 Kx=RSA      Au=RSA Enc=RC4(128)  Mac=SHA1
$ export hexc=0x00,0x05 && openssl ciphers -tls2 -V 'ALL:COMPLEMENTOFALL:@STRENGTH' | grep -w "$hexc" - | awk '{ print $3 }'
RC4-SHA
$ export hexc=0x00,0x05 && openssl ciphers -tls2 -V 'ALL:COMPLEMENTOFALL:@STRENGTH' | awk '/\<'"$hexc"'\>/ { print $3 }'
$

The old command finds my RC4-SHA cipher, the new one does not.
