[RFA] fix cygwin gdb.base/find.exp failures

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  I am still running the testsuite using 
expect version 5.26 from 2003,
because I never managed to get expect 5.43
to run on cygwin... (no more pty available error :( )

  This version has some specific troubles, limitations
or features that make some tests fail using that version
while they should not (or does it have to do with the
tcl version... not really sure, I remember having read once
something about the multiple evaluation differences
for quoted versus braced expressions...).

  gdb.base/find.exp is such an example.

  By a one line patch, I fixed the 17 failures I get otherwise
for this test.

gdb/testsuite/ChangeLog entry:

2009-01-26  Pierre Muller  <muller@ics.u-strasbg.fr>

	* gdb.base/find.exp: Set newline variable
	using quotes instead of braces to fix cygwin failures.
