Describe the Bug

Astro components are not POSIX compliant because if you add a new empty line at the end of the file, it gets converted to a space.

This code (Foo.astro):

<>foo</>(\n, new line)
(EOF, empty line)

If you call it like <p><Foo /></p>, the result is <p>foo </p> (with an ending space that affects the html render).

POSIX define a line as:

3.206 Line
A sequence of zero or more non- <newline> characters plus a terminating character.

So astro components should let you finish the file with an empty new line. Astro maybe needs to call trim() internally so it gets deleted and not converted into a space.
