It is more pedantically correct to terminate header names with : though
if whitespace follows you can omit it. The reason is that most printing
characters other than colon or whitespace are permitted in header names.
There is nothing wrong with a header line such as:
Funny-{indeed}-[yes!]-header: something
Thus, if you want to use $header_something in a context where white
space does not follow, you must use the terminating colon. Typically
this is in an expanded string such as
${if eq{$header_something:}{....}....
Without the colon there, the header name would not terminate at the }.
