We added a `.dir-locals.el` in commit: 9a77017d87
There's no need to have it per-file, with that people might think
to add other editors, which is the wrong direction.
Closes: #1206

zlib can return LZMA_BUF_ERROR, which indicates that either
the input or output buffer has size zero. This case should cause
the correct error to be passed back from g_converter_convert
to expand the relevant buffer. Since this error is ambiguous
as to which buffer is too small, an explicit check on the
output buffer size is added as well.
