1) Properly document e, f and m-flags in the manpage.
2) Clear up the code for the m-flag-handling. Add idiomatic
'/'-path-traversal as already seen in mkdir(1).
3) Unwrap the SWAP_BUF()-macro.
4) BUGFIX: Actually handle the f-flag properly. Only resolve
the dirname and append the basename later.
5) Use fputs() instead of printf("%s", ...).
It has become a common idiom in sbase to check strlcat() and strlcpy()
using
if (strl{cat, cpy}(dst, src, siz) >= siz)
eprintf("path too long\n");
However, this was not carried out consistently and to this very day,
some tools employed unchecked calls to these functions, effectively
allowing silent truncations to happen, which in turn may lead to
security issues.
To finally put an end to this, the e*-functions detect truncation
automatically and the caller can lean back and enjoy coding without
trouble. :)
It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).
This is also more consistent with the other suckless projects
around which don't use boolean types.
These used to live in TODO but we got rid off them. Make sure
we keep track of what we want to support by printing a message
when those flags are unimplemented.
