[nongnu] elpa/sweeprolog 6fd185fa1f 2/3: Use 'nil' for some 'defface's instead of ':inherit default'

[ELPA Syncer]

branch: elpa/sweeprolog
commit 6fd185fa1f135e39b81091fbe0626a75005b4dc0

    Use 'nil' for some 'defface's instead of ':inherit default'
    
    Change 'defface's that only specify inheritance from 'default' to
    empty (nil) definitions, such that the appearance of text these with
    faces can be determined by other faces applied to the same text.  This
    is important, for example, when using Sweep in Org mode source blocks.
