[nongnu] elpa/go-mode 4fabba6 464/495: Small fix for fontification of array types

[ELPA Syncer]

branch: elpa/go-mode
commit 4fabba6e20d2da78644087a19a23361cb3b7d20d
Author: Muir Manders <muir@mnd.rs>
Commit: Peter Sanford <psanford@sanford.io>

    Small fix for fontification of array types
    
    We weren't fontifying the type for array types like "[someConst]int". We now
    allow identifiers in the brackets.
    
    I also dropped the must-be-preceded-by-non-word case since I don't think it 
is
    necessary and it prevents fontification at the beginning of the line.
    
    Closes: #311 [via git-merge-pr]
