[nongnu] elpa/dockerfile-mode 89dba6d115 051/104: Treat = as punctuation.

[ELPA Syncer]

branch: elpa/dockerfile-mode
commit 89dba6d115848c5eb112c26550946150fe597806

    Treat = as punctuation.
    
    Previously, = was treated as a symbol character. This prevented things
    like highlight-symbol-mode and isearch-forward-symbol being able to
    find variables defined with `ENV FOO=1`.
