shared: path-util - try to make PATH_FORECH_PREFIX look less wrong
We replace the idiom "X && !(*foo = 0)" with "X && ((*foo = 0), true)". This is not a functional change, but should hopefully make it less likely that people and static analyzers believe there is a typo here (i.e., to make it clear that the intention was not "X && *foo != 0"). Thanks to David Herrmann for the suggestion.
