master e7e7ef1: Fix fill-paragraph in asm-mode

[Lars Ingebrigtsen]

branch: master
commit e7e7ef15886ce28d1d1873164e7ee17a6a5878e0
Author: Mattias M <mattias@marka.ee>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix fill-paragraph in asm-mode
    
    * lisp/progmodes/asm-mode.el: The value of fill-prefix ought to be nil
    not "\t" so that fill-context-prefix can do its thing. In fact,
    fill-prefix does not have to be set at all becuase asm-mode derives
    from prog-mode and fill-prefix is set in simple.el.
    
    * test/lisp/progmodes/asm-mode-tests.el: Add relevant test (bug#41064).
