Tags: patch This patch makes sh-execute-region to send the region to the subshell specified by the current file interpreter. Without it Emacs would run the region using the default user shell which is probably not what you would expect if you are editing scripts made for other shells. Beware that I have not tested it on Windows or TRAMP. BTW it is nice to edit code older than me 😀.
