History: no prompting on exit errors, because making the user hit Enter when

there's an error saving history state at exit is pointless and annoying.
Just notify the user and move on.
Patch by Mike Frysinger, tweaked and extended by Benno.

ChangeLog

 2015-12-23  Mike Frysinger  <vapier@gentoo.org>
 	* doc/syntax/autoconf.nanorc: Handle .m4 files too, add the "elif"
 	keyword, handle dnl comments better, and mark trailing whitespace.
+	* src/files.c (save_history, save_poshistory): Don't make the user
+	hit Enter when there's an error saving history state at exit; it is
+	pointless and annoying.  Just notify the user and move on.
 
 2015-12-23  Christian Weisgerber  <naddy@mips.inka.de>
 	* configure.ac: AC_CHECK_HEADERS_ONCE() is very special and cannot be

src/files.c
