* generic/tclIOUtil.c (TclGetOpenMode): Added the flag O_APPEND to
the list of POSIX modes used when opening a file for
'a'ppend. This enables the proper automatic seek-to-end-on-write
by the OS. See [Bug 680143] for longer discussion.
* tests/ioCmd.test (iocmd-13.7.*): Extended the testsuite to check
the new handling of 'a'.
