* Version 5.3.0.
+ tac would exit immediately upon I/O or temp-file creation failure.
+ Now it continues on, processing any remaining command line arguments.
+
* src/tac.c: Include quotearg.h.
Use quotearg_colon in most diagnostics.
(copy_to_temp): Rewrite not to exit upon I/O or temp-file-creation
(tac_nonseekable): Return false also if copy_to_temp fails.
[DONT_UNLINK_WHILE_OPEN]: Add a FIXME comment explaining that
using atexit like this is wrong.
+ * NEWS: Document this.
* tests/misc/tac-continue: New test for this.
* tests/misc/Makefile.am (TESTS): Add tac-continue.
