Subject: cmd/go: adjust regexp that cleans cgo-related errors
X-Git-Tag: go1.9beta1~31
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=4c028e565071c80803c975ca9c6431dbc6bb2a88;p=gostls13.git

cmd/go: adjust regexp that cleans cgo-related errors

The compiler now also prints column information - make sure we use
the correct regexp for compiler error cleanups. Accept both, error
positions with columns and without, since column printing may be
disabled with -gcflags=-C.

Fixes #20628.
