indent(1): restore working -pcs

My previous indent(1) commit accidentally broke the -pcs option (which adds
space between function name and opening parenthesis in function calls) by
copying all but one of a few conditions in an if clause. Reinstate the
condition.

Add a regression test to lower the chances of breaking it again.

Correct a comment with description of what the option does.
