[nongnu] elpa/eglot-inactive-regions 4881848cbc 1/2: check next-single-property-change return code

[ELPA Syncer]

branch: elpa/eglot-inactive-regions
commit 4881848cbcc49fa6291bbefdeae6b55b767bc95f
Author: Filippo Argiolas <filippo.argio...@gmail.com>
Commit: Filippo Argiolas <filippo.argio...@gmail.com>

    check next-single-property-change return code
    
    next-single-property-change returns nil if face does not change til the
    end of a fontification region. This led to jit-lock errors and
    unshaded regions with c-ts-mode and darken-foreground. Properly handle
    return code. Fix #2.
