er, yes, sorry:-)

also wsl avoids getting the problem by default by not putting the windows
path at the end of the linux one.

yes cygwin adds the windows path, probably because, especially in early
it was less complete and you more often needed to mix and match, anyway it
is what it is.

yes if they were explicitly blacklisted or only a normalised path of
/usr/bin was set
then windows curl wouldn't be found and you'd get the existing message for
no wget/curl found
rather than some lower level fail message from windows curl doing the wrong
