Hello.

I received this from the Debian bug system:

Subject: Bug#535601: Indent changes file twice when called twice

Package: indent
Version: 2.2.10-1
Severity: normal

We have found that indent changes some files back and forth. Here is an
example that reproduces the problem:

jzobel@test$ cp test_indent.c test_indent.c.org
jzobel@test$ indent -kr --no-tabs test_indent.c
jzobel@test$ diff test_indent.c test_indent.c.org 
18,19c18,19
<     return
bar->bar->bar->bar->bar->bar->bar->bar->bar->bar->bar->bar->
<         bar->bar->bar->bar->bar;
---
>     return bar->bar->bar->bar->bar->bar->bar->bar->bar->bar->bar->
>         bar->bar->bar->bar->bar->bar;
jzobel@test$ indent -kr --no-tabs test_indent.c
jzobel@test$ diff test_indent.c test_indent.c.org 
jzobel@test$ 

Sincerely,
Joachim
