[elpa] master 2b8d33f 05/14: Handle invalid history match in ggtags-global-filter

[Leo Liu]

branch: master
commit 2b8d33f3284c4af2011a9d30799cdb6be8fcf4f5

    Handle invalid history match in ggtags-global-filter
    
    by jumping to first error instead.
    
    For example when a history match is set on the second match of all
    matches and the search later turns up only single match, ggtags will
    fail to jump to match. To make things worse ggtags-global-handle-exit
    will kill the *ggtags-global* buffer leaving users with no opportunity
    to move to a valid match.
