I have been going through some answers to a vimgolf, and stumbled upon this regex:
The regex (without unrelated keystrokes) is
/\_W*/-/. The manual indicates that:
\W stands for
non-word character: [^0-9A-Za-z_]
\_x Where "x" is any of the characters above: The character class with
\_W is non-word characters with end-of-line added.
How does that put the dashes between the characters? Is there a hidden metacharacter between each character in vim text?
