The symbol + in c++-mode is stripped

[taquangtrung]

Hi,

I notice that Cyphejor strips the + symbol, hence c++-mode is converted to c mode.

This is due to the code at this line:

cyphejor/cyphejor.el

Line 84 in cf58099

(let ((words (split-string (downcase old-name) "[[:punct:]]" t))

Currently, I change the regexp "[[:punct:]]" to the regexp [\b\\-] to split words by only the word boundary and the - symbols to avoid + from being removed.

(let ((words      (split-string (downcase old-name) "[\b\\-]+" t))
  ...

Could you advise if this is a suitable fix?

I can also create a PR if this is needed

I think it is a good idea, PRs are welcome!
