Does any programming language assign meaning to trailing spaces? - whitespace

Question

There are a number of programming languages such as Python and F# that assign semantic meaning to leading spaces, so that if a line of code has leading spaces removed, it can break the whole program.
But what about trailing spaces?
Are there any programming languages that assign semantic meaning to spaces that come at the end of a line, just before the line feed or carriage return character?
(Let's assume I'm excluding languages that are nothing but space, e.g. Whitespace.)

Answer 1

T-SQL is a language that's trailing whitespace sensitive, both in identifiers and multiline strings, and still used in many enterprise applications
-- Warning: horrifying, don't ever do this
CREATE TABLE [Table
Name](
[My
field] INT
);
SELECT * FROM [Table
Name]; --Works;
SELECT [My
field] FROM [Table
Name]; --Works
SELECT [My
field] FROM [Table
Name]; --Fails, lacks trailing space in field name
SELECT [My
field] FROM [Table
Name]; --Fails, too few trailing spaces in table name

Answer 2

Markdown treats some trailing whitespace specially. When a line ends with two or more spaces, a line break <br> is inserted to break up a paragraph.
This rule is not well-known, so it may be triggered unintentionally and some linters disallow it by default (MD009 no-trailing-spaces):
This rule is triggered on any lines that end with unexpected whitespace. To fix this, remove the trailing space from the end of the line.
Note: Trailing space is allowed in indented and fenced code blocks because some languages require it.
The br_spaces parameter allows an exception to this rule for a specific number of trailing spaces, typically used to insert an explicit line break. The default value allows 2 spaces to indicate a hard break (<br> element).
Note: You must set br_spaces to a value >= 2 for this parameter to take effect. Setting br_spaces to 1 behaves the same as 0, disallowing any trailing spaces.
As an example, these markdown paragraphs (middle dot represents space):
Three···
trailing spaces
Two··
trailing spaces
One·
trailing space
No
trailing spaces
A··
mix
of··
spacing··
are rendered as such:
Three
trailing spaces
Two
trailing spaces
One
trailing space
No
trailing spaces
A
mix
of
spacing
