Formatter leaving unwanted characters

What it should do

stripDashes(text) should remove every dash, so stripDashes("a-b-c") returns "abc".

What goes wrong

stripDashes("a-b-c") returns "ab-c" — only the first dash is removed.

Hints

This is a mutation and copying bugs bug

Assignment does not copy, a shallow copy still shares its contents, and mutating methods return None.
