Use alloca_{rawbytes,ibytes} in #'copy-file, #'insert-file-contents-internal src/ChangeLog addition: 2014-01-20 Aidan Kehoe <kehoea@parhasard.net> * fileio.c (Fcopy_file, Finsert_file_contents_internal): Use alloca_{rawbytes,ibytes} here instead of the implicit alloca on the stack; doesn't change where the buffers are allocated for these two functions, but does mean that decisions about alloca vs. malloc based on buffer size are made in the same place (ultimately, the ALLOCA() macro).
