Tweak the way appendModuleInlineAsm works, so you aren't obliged

to append a newline when using setModuleInlineAsm in case later
someone calls appendModuleInlineAsm - make newline handling fully
automatic.  In case anyone is wondering there is only one user of
appendModuleInlineAsm: the dragonegg plugin.
