The following would fail with Zsh instead of Bash :
$ source ./scripts/checkpatch_inc.sh
$ checkpatch HEAD
Unknown option: typedefsfile typedefs.checkpatch
Usage: .../scripts/checkpatch.pl [OPTION]... [FILE]
By setting xtrace in the _checkpatch() function, we can see the built
command is interpreted differently depending on the shell:
$CHECKPATCH $CHECKPATCH_OPT $typedefs_opt -
In Zsh:
/scripts/checkpatch.pl '--typedefsfile typedefs.checkpatch' -
In Bash:
/scripts/checkpatch.pl --typedefsfile typedefs.checkpatch -
Bash differs from Zsh when it comes to word splitting for unquoted
parameters expansions.
One solution is to use `eval` to execute the built command.
