* Problems with installed bash completions were found:
* spatch: 'have' command is deprecated and must not be used.
* spatch.opt: missing alias (symlink) for completed command.
* For more details on installing bash-completions, please see:
1. remove the 'have' call. It is not necessary, just enable completions unconditionally,
2. bashcomp_alias spatch spatch.opt
3. you are also installing 'spatch.byte' but that one is not mentioned in the completion file.
