Make the indentation variables local to this buffer.
Normally they already are local. This command is provided in case
variable `sh-make-vars-local' has been set to nil.
To revert all these variables to the global values, use
command `sh-reset-indent-vars-to-global-values'.
Controls whether indentation variables are local to the buffer.
If non-nil, indentation variables are made local initially.
If nil, you can later make the variables local by invoking
command `sh-make-vars-local'.
The default is t because I assume that in one Emacs session one is
frequently editing existing scripts with different styles.
