Subject: [PATCH] fix: Empty text editor has no cursor. (#1976)

Even if focus is given to the pattern editor the cursor will not show
until the editor contains printable chars.

### Problem description
I was using the wrong condition to enter the loop that skipped the
default empty document.

### Implementation description
The fix was to check if there are lines of text that need to be
processed even if they are empty.
