Subject: cmd/gofmt: Ignore file not found errors.
X-Git-Tag: go1.7beta1~1841
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=3ddfaa5653cfc5c8663319d017a5fb4de97814f4;p=gostls13.git

cmd/gofmt: Ignore file not found errors.

gofmt prints an error to stderr when a file is deleted during its
`filepath.Walk()', which can happen in builds that change the tree
concurrently with gofmt running.
