func Match(pattern, name string) bool

Match reports whether name matches the shell pattern. This is a strip down version of Go's `path.Match` https://pkg.go.dev/path#Match Call a "fixword" a maximal portion of the pattern consisting only of regular characters and ?s. So a fixword has to begin after * or at the beginning of the string, and it has to end before * or at the end of the string. Each fixword matches a fixed length of string. Now a pattern is a list of fixwords separated by *s. Consider a fixword that is not preceded by a *; that's an easy match to find because it can only be at one place. Consider a fixword that is preceded by a *; if it matches at multiple places then it is always safe to match it at the first possible location: either the pattern ends after that fixword in which case there's only one possible location, or the pattern continues with *, in which case that * can "expand" to pick up all characters and the next match of the fixword.
