fixplurals - remove redundant parameter and result types from function signatures
For example, the following function signature:
func fun(a string, b string) (c string, d string)
becomes:
func fun(a, b string) (c, d string)
after applying fixplurals.
% go get -u github.com/davidrjenni/reftools/cmd/fixplurals
% fixplurals [-dry] packages
Flags:
-dry: changes are printed to stdout instead of rewriting the source files
