Reading your description, shouldn't this be:
- if (!(toys.optc==0 && (toys.optflags & (toys.optflags-1))==0) && toys.optc!=1)
- space = 7;
+ if (toys.optc>1 || (toys.optflags&(toys.optflags-1))) space = 7;
optc 0 means stdin, optc 1 means a single file, so optc>1 means multiple
lines of output, and then your trick for the "one flag only"...
Which means that the same 2 tests that TEST_HOST=1 fails with also fail here,
except we're indenting with tabs and they're doing readahead. But the "indent
or not indent" decision's the same this way...

Yeah, that one. Tabs instead of measured spaces, but it sounds like that's
what older versions used to do and we're well past what posix says anyway?
