• Commands: Improve :GoImport to trim spaces when including import paths of form "fmt "
• Commands: Fixed :GoRun to display errors when g:go_dispatch_enabled was enabled
• Commands: Fixed :GoDrop displaying "Not enough arguments" (regression)
• Commands: Fixed :GoErrCheck not showing PASS message if the command was successful
• Commands: Fixed :GoErrCheck not executing in the directory of the currently edited file
• Commands: Close quickfix window after a successful second round of :GoInstall
• Internal: Avoid setting filetype twice. Previously it was doing it twice, which was expensive
• Internal: Improve handling of GOPATH's with trailing / characters, such as /home/user/go/
• Oracle: Escape files passed to oracle command. This could lead to some serious things.
• Oracle: Clear g:go_oracle_scope when the scope was reseted. Previously it was set to empty string, which was causing false positives.
