unzip may be set to "" on some Linux systems, which causes
remotes::install_remote()
to generate an obscure error that is a bit tedious to troubleshoot:Since "internal" unzip always, work this patch makes sure that is
used also when unzip is "".
See https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17255 for
more details on why unzip may become "".
PS. Yes, one could force
options(unzip = "internal")
on such systems, and ideallyutils:::.onLoad()
should do that, but until then this is user friendly patch.
