Add support for windows verbatim disk paths

[nico-abram]

Fixes #111

[nico-abram]

Replaced matches! with an if-let. CI runs on an old rustc so it was failing and I don't know what glob's MSRV policy is.

Pulled this patch locally and confirmed it addresses the issue observed in getzola/zola#1932.

Happy to help out, should an extra pair of hands be needed to merge and release.

Seems you disabled access to this branch, could you rebase to trigger the latest CI?

[nico-abram]

Rebased.

Hmm, that's weird, maybe I force-pushed for rebasing and that's a culprit.

Anyway, this LGTM, thank you for the PR and sorry for the long delay!

Just ran into the exact same issue fixed here after hunting down why a buildscript didn't behave properly on Windows.
Any chance this could get into a bug-fix release any time soon? :)
