Regular expression. Basically, if you have a character, followed by one or 
more of itself, replace it with itself:

s/ <--- replace
(.) <--- match anything, store it in first backreference
\1 <--- first backref
+ <--- one or more
/ <--- replace with
\1 <--- first backref
/g <--- match more then once per line
