Subject: pgindent: ensure all C files end with a newline.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=79ac82125ef6608b8a1c7e089eea17476537467c;p=thirdparty%2Fpostgresql.git

pgindent: ensure all C files end with a newline.

Not only is this good style, but it dodges some obscure bugs within
pg_bsd_indent.  We could try to fix said bugs, but the amount of
effort required seems far out of proportion to the benefit.
