MaxSem e97180e5f6 Revert "Make eval.php try to handle newlines in code"
Completely broke the script for me.

<TimStarling> MaxSem: that was a pretty crazy change
<TimStarling> fancy trying to detect the end of a statement by shelling out to detect parse errors
<TimStarling> maybe just revert that?
<TimStarling> we can probably do a better job with a few regexes
<TimStarling> I wonder how php -a does it

This reverts commit f0ae292da7.

/**
* This script lets a command-line user start up the wiki engine and then poke
* about by issuing PHP commands directly.
*
* Unlike eg Python, you need to use a 'return' statement explicitly for the
* interactive shell to print out the value of the expression. Multiple lines
* are evaluated separately, so blocks need to be input without a line break.
* Fatal errors such as use of undeclared functions can kill the shell.
*
* To get decent line editing behavior, you should compile PHP with support
* for GNU readline (pass --with-readline to configure).
