this can be fixed by changing just one line in fileconverters.c; if the @@JOBTITLE@@ placeholder is prefixed by '\"' (and only prefixed), then the argument prep logic wraps it suitably. (it's still a pretty ugly mess, what with unnecessary detours via a shell but that's a separate story.) the attached patch makes that change, and a quick check with strace confirms that a2ps is now called correctly: 25389 execve("/bin/bash", ["/bin/bash", "-c", "a2ps -1 --medium=A4dj --center-title=\"Documentation for the Ricoh SP C250DN PS\" -o -"], 0x7fffc24477b8 /* 38 vars */ <unfinished ...> ... 25389 execve("/usr/bin/a2ps", ["a2ps", "-1", "--medium=A4dj", "--center-title=Documentation for the Ricoh SP C250DN PS", "-o", "-"], 0x55f407b0f1b0 /* 37 vars */) = 0 >At the same time, I don't see any code generating the docs I am looking for, it >seems commented out. So maybe that is also broken? yes, it's nonexistent: they never migrated the documentation extraction code from version 3.x's perl (where it was very simple to do) to version 4.x's c codebase (where it's a bit more work) - but the did leave the broken/incomplete '-o docs' in the code and the documentation :-( i recreated something not entirely unlike that doc extractor earlier today and will submit it in a separate bug regarding the misleading docs and code leftovers.
