[nongnu] elpa/go-mode a13b814 448/495: Add option to reuse a single buffer for godoc

[ELPA Syncer]

branch: elpa/go-mode
commit a13b8146bfde207513327d95e5e85cefadf99832
Author: Peter Gardfjäll <peter.gardfjall.work@gmail.com>
Commit: Peter Sanford <psanford@sanford.io>

    Add option to reuse a single buffer for godoc
    
    This introduces a customization variable 'godoc-reuse-buffer' which, when
    non-nil, makes godoc-at-point reuse the same ("*godoc*") buffer to write 
output
    from all invocations. The default behavior (when nil), is still to write 
each
    output to a separate buffer (*godoc <path>*).
    
    Closes: #295 [via git-merge-pr]
