Move the code to detect shell scripts and binary executables from mingw_access to a separate function, has_exec_format. Call this function in do_lstat to decide whether to set the executable bits in the file mode. This will slow down stat but has a couple of advantages: - shell scripts are highlighted in ls output - the test applet can use stat(2) to detect executable files The new function is used to handle another corner case in spawnveq: binary executables without the usual .exe extension are only run by spawnve if the file name ends with '.'. Two minor changes: - file_is_win32_executable has been renamed add_win32_extension to clarify what it does - a call to file_is_executable has been removed from find_command in ash as it resulted in unhelpful error messages.
