Hi,

Using Guix aabfddb, consider:

$ guix show -L src/example hi

$ guix edit -L src/example hi
guix edit: error: file 'src/example/first.scm' not found in search path ("src/example" "/gnu/store/yzib23ah0rlmim0j4737g2wrhx1r1q3r-guix-module-union/share/guile/site/3.0" "/gnu/store/84rvhd3j7pfqrh7717cv7ddv2dc8xad5-guile-3.0.9/share/guile/3.0" "/gnu/store/84rvhd3j7pfqrh7717cv7ddv2dc8xad5-guile-3.0.9/share/guile/3.0" "/gnu/store/84rvhd3j7pfqrh7717cv7ddv2dc8xad5-guile-3.0.9/share/guile/site/3.0" "/gnu/store/84rvhd3j7pfqrh7717cv7ddv2dc8xad5-guile-3.0.9/share/guile/site" "/gnu/store/84rvhd3j7pfqrh7717cv7ddv2dc8xad5-guile-3.0.9/share/guile" "/home/simon/.guix-profile/share/guile/site/3.0" "/home/simon/.config/guix/profiles/emacs/emacs/share/guile/site/3.0" "/home/simon/.guix-profile/share/guile/site/3.0" "/home/simon/.config/guix/profiles/emacs/emacs/share/guile/site/3.0")

The issue is that the procedure 'search-path' returns #f.  It looks similar as
fixed bug #42543 [1] by d10474c38d58bdc676e64336769dc2e00cdfa8ed.

Here, I do not know how to avoid 'canonicalize-path' when 'search-path'
returns #f because some relative.

WDYT?
