Subject: READ_BUF_SIZE → sizeof read_buf
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=8e5ef348968f9cccef21f83b940c0ffad2ebe31d;p=emacs.git

READ_BUF_SIZE → sizeof read_buf

* src/fileio.c (Finsert_file_contents): Minor refactoring.
This should help future patches which distinguish read_buf’s size
from other uses of READ_BUF_SIZE which may change.

(cherry picked from commit ae30a61c74215c3e02fb3c0d603894457a4cfef5)
