indent gives unstable output

[Alex Bligh]

With the text below, which I have also attached (I realise the mailing
list will probably strip that), indent flips between two states.

This is irritating, as one can't then use indent as a matter of course
before committing to a version control system.

$ indent test.c ; ls -la test.c ; indent test.c ; ls -la test.c ; indent 
test.c ; ls -la test.c ; cp test.c test2.c ; indent test.c ; ls -la test.c 
; diff -u test.c test2.c
