[nongnu] elpa/visual-fill-column a93dc5fc64 117/137: Do not set `visual-fill-column--min-margins` if already set.

[ELPA Syncer]

branch: elpa/visual-fill-column
commit a93dc5fc64340d8abda1272f67d46d4cc09a4c85

    Do not set `visual-fill-column--min-margins` if already set.
    
    This should hopefully prevent the window parameter `min-margins` from 
getting a
    value that prevents `split-window-right` from working. See Github issue #49.
