Inline scripts are not saved with a final carriage return

A Bamboo user of ours was recently running a task in Bamboo that executed an inline tcsh script (we have to use tcsh here for historical reasons before anyone links to http://www.faqs.org/faqs/unix-faq/shell/csh-whynot).

The script was

exec tcsh -f $0 $*

foreach x (a b c)
  echo $x
end

The output was simply

a

Investigation showed that adding a comment after the final line resulted in the correct output. However when adding just a carriage return on it's own to the script the faulty output was seen again. Looking at the script after a save, trailing empty lines have been stripped.

According to some of the developers here, files should always be saved with a trailing EOL as a number of gnu tools require it.

The workaround for this is trivial however so this is not a major issue but I thought it worth reporting.
