4470	SHELL: fix exit-code and add 'strip-eol' option	codemonkey@…	René Rivera	"This patch applies WIFEXITED() and WEXITSTATUS() to the exit code returned by the SHELL rule when the 'exit-code' option is used.

Without these (on Linux, at least) the exit code is left-shifted 8 bits so that an actual exit code of 1 shows up as 256 and an actual exit code of 2 shows up as 512 (etc).

This patch also adds a new 'strip-eol' option to the SHELL rule.  This causes trailing white space (most importantly, newlines) on the command's output to be removed before it's returned to the caller.  Note that embedded newlines are left intact; these are needed if the user wants to echo the output and it contains multiple lines.

Note that 'strip-eol' has no practical effect if 'no-output' is also used.

Usage example:

  local foo = [ SHELL ""./foo.sh"" : exit-code : strip-eol ] ;
