Opening manpage file by path results in UriError

[GitMensch]

As an example: "open manpage" then "/home/me/gcc/gcc/cobol/gcobol.1", leading to

[error] Error: [UriError]: If a URI does not contain an authority component, then the path cannot begin with two slash characters ("//")

the manpages output pane shows

openFromInput called with text: /home/me/gcc/gcc/cobol/gcobol.1

so... something seems to encode the / wrongly.
