Excellent... one issue though, it seems that it trims some of the
line with it on certain cases. I use smarty templates in some of my
work, and some lines have text like:

{$var|modifier}

after using the command, $var disappears (everything before the pipe,
not including the left curly brace)

When Simon translated Steve's Perl code into Ruby, he missed out a crucial line:

# Escape anything in the line that might be mistaken
# as a snippet token.
$line =~ s/([\$\\`])/\\\1/g;
