        The "." does not include the newline ("$") so, you must count it
        in the regx:


EXTN="hta|com|pif|vbs|vbe|js|jse|exe|bat|cmd|vxd|scr ... and more ..."
        (BTW you don't need "scr" and "SCR")
.
.
.
* $ ^Content-Type:(.|$)*=(.|$)*\".+\.($EXTN)\>


        I didn't check it because I do more expensive but readable,
        sed(1) makes the Content-x records to be one line:

| sed -e ':a' -e '$!N;s/^\(Content-.*\)\n[ ^I][ ^I]*/\1 /;ta' -e 'P;D'

        I know it's extra, it's not good idea, but it makes the records
        to be much easier to work.
