Which docs say this? I looked at Doc/lib/libstdtypes.tex to get the
semantics:
\begin{methoddesc}[file]{readline}{\optional{size}}
... If the \var{size} argument is present and
non-negative, it is a maximum byte count (including the trailing
newline) and an incomplete line may be returned. ...
\end{methoddesc}
\begin{methoddesc}[file]{readlines}{\optional{sizehint}}
... If the optional \var{sizehint} argument is
present, instead of reading up to \EOF{}, whole lines totalling
approximately \var{sizehint} bytes (possibly after rounding up to an
internal buffer size) are read.
\end{methoddesc}
Neither text mentions the special cases for -1 and 0 in each function.
Fixing the patch to get this right is trivial, but I think the docs
need to be updated to mention this.
