Just use / in this specific case which might already happen if the user's home directory is blank in the passwd(5) file.
More to come. Namely, error context which changes throughout the program (ie output to either stderr or to the command/status window) and consolidating the debug code, as well.
Specific "modules" should include what they really need and not rely on some other header including files. Obviously, now, headers need to be explicitly included.
Might be better, in the future, to append -Wformat=2 to CFLAGS and also use the printf format attribute.
Which, in my opinion, is a good thing because, as a consequence, there's less pre-processor goo in the tree.
From now on, there's no need to specify the relative path of local header files.
It might generate a SIGSEGV exception if it's accessed. Caught by the new wrapper function.
Now, with error contexts, the execute function can, also, be called when parsing the configuration file, without having to worry about where to output its messages. That is, when parsing the configuration file, the messages are printed to standard error and, afterwards, they get painted to the command/status window.
The fparseln(3) function already returns NULL on EOF. Check it and move the ferror(3) call outside the loop.
It already gets printed by the error functions.
