            Bug ID: 79642
           Summary: space instead of tab in lang.opt
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go

  Target Milestone: ---

In go/lang.opt, the option fgo-relative-import-path= is defined other than all
others.

fgo-relative-import-path=
Go Joined RejectNegative
-fgo-relative-import-path=<path> Treat a relative import as relative to path.

There is a space between "<path>" and "Treat". All entries should have a tab
here, to allow for proper table formatting.

This invisible typo should have been caught automatically when parsing that
file.
