I'm test-driving Emacs 25.1 and have noticed that a simple
concat command, which used to work in v.24 (and v.23), doesn't work in v.25.1:
(setq yas-snippet-dirs (concat user-emacs-directory "snippets"))
In v.25.1 I get the following error message:
byte-code: Wrong type argument: listp, "~/Dropbox/emacs/snippets"
To make it work in v.25.1, I need to do call the function thus:
(setq yas-snippet-dirs (concat user-emacs-directory '("snippets")))
So my question is, why doesn't the latter work in Emacs 25.1 anymore? (Or alternatively, is the former the correct way actually?)
