fmt: handle negative width/prec when supplied as an argument Negative width arguments now left align the way a minus-width in the format string aligns. The minus in the format string overrides the sign of the argument as in C. Precision behavior is modified to include an error if the argument is negative. This differs from a negative precision in a format string which just terminates the format. Additional checks for large magnitude widths and precisions are added to make the runtime behavior (failure, but with different error messages), more consistent between format string specified width/precision and argument specified width/precision.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
