Jim Meyering c3cac089b1 Use comma-separated list in ./configure --help output.
* configure.ac: Map commas to spaces in excluded-program list.
Use a comma-separated list, not a space-separated one.
* m4/include-exclude-prog.m4 (gl_INCLUDE_EXCLUDE_PROG):
Expect list of program names to be comma-separated.
