t0025 weird behaviour on NonStop ksh/bash

Ok, I'm sure that this is not a git problem, but there is an assumption about echo behaviour in t0025 that may not be correct. When executed from a shell function on the HP NonStop platform under ksh and bash, the LFonly file annoyingly contains cr-lf not just lf. This causes sub-test 4 to fail. Weirdly, this does not happen from an interactive shell. My proposed solution, in t0025-crlf-auto.sh, to this is to make it explicit that bad behaviour on the part of echo should be dealt with severely, as in:

        for w in Hello world how are you; do echo $w; done | tr -d '\r'

instead of 

        for w in Hello world how are you; do echo $w; done >LFonly

which is a no-op on platforms that behave themselves in this situation. Is this the proper approach?
