[ELPA Syncer]

branch: elpa/go-mode
commit 8796ec6ebf8c77c3d6f5c7ebd8902a91e9e8eb57
Author: Muir Manders <muir@mnd.rs>
Commit: Peter Sanford <psanford@sanford.io>

    indent: fix floating point literal with trailing point
    
    Now we don't mistake "1234." for a dangling ".". Normally one
    adds the zero explicitly, but this is valid and appears once in the
    standard library.
