However, to aid in formatting template source code, if an action's left
delimiter (by default "{{") is followed immediately by a minus sign and white
space, all trailing white space is trimmed from the immediately preceding text.
Similarly, if the right delimiter ("}}") is preceded by white space and a minus
sign, all leading white space is trimmed from the immediately following text.
In these trim markers, the white space must be present:
