txt-document: a colon plus space in the very first line after the first expression shows different background color #30

Steps to reproduce

open Geany (as css: extra-media.css)
put a txt-document in focus
type in the very first line completely on the left: tzz:

Result The first line has a different background color. And the whole text of the document appears in the preview.

Expectation There should be no different background color. And there should be an empty preview.

This is caused by the email header detection. The tzz: is treated similarly to other headers, like Subject:.

I've modified regex to reduce false positives when detecting headers. The PPA has been updated. You can control the style that is used for headers with the geany_preview_headers rules in preview.css.

I can confirm that issue is fixed.
