Oops1: Variable "$xml" is not imported at (eval 640) line 718

I had to insert 4 blanks in front of the my command in
code/common/android_server.pl
lib/xml_server.pl

my $html = <<eof;

<?xml version="1.0" encoding="utf-8" standalone="yes"?>

eof

Without the leading blanks, the line with my gets removed and starting misterhouse results in

I just did a git clone -b master and was surprised the issue still exists. Several lib and code files have
my $json <<eof
...
eof

and result in

This causes the json_server to fail, which in turn makes ia7 less than responsive. I am not a star at git, so I will not attempt a pull request, however, here are the diffs
