[nongnu] elpa/go-mode 259110b 396/495: Use a named function for before-change-functions.

[ELPA Syncer]

branch: elpa/go-mode
commit 259110bfd7acb62196b09487d0883429b444bf1b
Author: Matt Armstrong <marmstrong@google.com>
Commit: Dominik Honnef <dominik@honnef.co>

    Use a named function for before-change-functions.
    
    Create go--reset-dangling-cache-before-change and add that to
    before-change-functions, rather than adding a lambda.  The effect is the
    same, but this allows people to easily find the file responsible when
    looking at before-change-functions in Emacs' help system (such as with
    describe-variable).
    
    Closes: gh-159 [via git-merge-pr]
