fix: keep a shell prompt whose spaced working directory ends in $ out of a spaced path link (release review)

spacedFilePathOnLine() refused only a FIRST word ending in `$`, so `/mnt/c/My Docs$ ls notes.md`
and `/mnt/c/Users/me/OneDrive - Contoso/proj$ code notes.md` linked the whole line. Any earlier
word ending in `$` now refuses the candidate, and both lines link what master links.
