There is a new pull request by gandalf3 against master on the void-packages repository

https://github.com/gandalf3/void-packages master
https://github.com/void-linux/void-packages/pull/42850

set null IFS in v* commands
without this, if `<pattern>` arguments contain whitespace, word splitting causes the argument to be split unexpectedly.

for example:
    `vcopy 'Spacey Folder/*.ttf' usr/share/TTF/`

calls something equivalent to
    `cp "Spacey" "Folder/*.ttf" usr/share/TTF/`

which of course fails.

i couldn't find a way to escape word splitting from outside, aside from setting `IFS`.
i'm not at all confident this won't break anything else in install.sh, but if it doesn't, i think it would be nice to preserve the expectation that `<pattern>` arguments are just pure globs.
