 **Features**:
 
 - `zsh` is now invoked using `zsh +o nomatch` for better portability across
-  shells. This prevents zsh from erroring when wildcard patterns find
-  no matches. Wildcards can be used, for example, to implement a
-  custom `clean` command that feeds `rm -f` using wildcard patterns,
-  but these commands would generate errors without disabling `nomatch`.
-  The zsh `nomatch` option is a less useful option for non-interactive use
-  so we disable it unconditionally.
