Tiny builds have the :finish command all right, what they lack is
expression-evaluation, which is needed for the :if statement. So, in a
tiny build, the whole scope of an :if statement, from :if to :endif, is
handled as a nestable comment, see ":help no-eval-feature".

To make sure your script isn't sourced by tiny builds, just wrap the
whole script in ":if 1" ... ":endif".

OTOH, in order to have some statements interpreted _only_ by builds
without expression evaluation, place them at the end of your script,
this way:

if 1
finish
endif
" come here only with Vim builds without expression evaluation

Best regards,
Tony.
