fix for PR gdb/15995
This patch fixes PR gdb/15995.
The bug here is that gdb's printf command does not flush the output
stream. This makes a printf that is not newline-terminated interleave
incorrectly with other forms of output, such as that generated via a
call to an external program using "shell".
I note that the "output" command already does this flushing.
The fix is to call gdb_flush in printf_command.
Built and regtested on x86-64 Fedora 18.
New test case included.
PR gdb/15995:
* printcmd.c (printcmd): Call gdb_flush.
* gdb.base/printcmds.exp (test_printf): Test printf flushing.
