bug#55344: ftw thinks readable directories are unreadable if "other" don't have read permission

[Saad Rhoulam]

I am also experiencing this issue on Guile 3.0.9, guix on Ubuntu 22.04, 
amd64 architecture. It won't descend into a directory unless it has o+rx 
permissions set.

bug#56413: [PATCH v3 1/1] scm_i_utf8_string_hash: compute u8 chars not bytes

[Ludovic Courtès]

Hi Rob,

Still LGTM, please push!  :-)
