[PATCH]: missing check in gas/app.c

[Arnold Metselaar <arnold.metselaar@planet.nl>]

Hello

While working on as for target Z80, I noticed that a check for a 
full buffer was missing after an optimised copy in 
do_scrub_chars() in gas/app.c 
A patch is below, it works with the assembler for Z80.

Side note: I sent the copyright assignment for binutils to FSF, 
but I haven't heard from them yet.
