[nongnu] elpa/go-mode 775c77a 241/495: immediately store match data in go-unused-imports-lines

[ELPA Syncer]

branch: elpa/go-mode
commit 775c77a1b32e6012c55c59a8195483aff9f5bed4
Author: Iwasaki Yudai <yudai.iwasaki@ntti3.com>
Commit: Dominik Honnef <dominik@honnef.co>

    immediately store match data in go-unused-imports-lines
    
    Calling other functions, such as file-truename in our case, can
    overwrite the match data.
