Unexpected change in path conversion behaviour after #143

After #143, my xmllint command has broken:

(msys2-runtime 3.4.6-2)

$ xmllint --xpath 'string(settings/servers/server[id = "gitlab"]/configuration/httpHeaders/property/name)' ~/.m2/settings.xml
XPath error : Invalid expression
string(settings/servers/server[id = "gitlab"]C:/msys64_b/configuration/httpHeaders/property/name)
                                             ^
XPath evaluation failure

because the space in the argument somehow means that the path conversion behaviour is triggered for the next part of the argument, despite the whole thing being quoted.

I've managed to reduce it to a minimal example below:

It's not quite clear from #143 whether this was intentional or not, certainly the behaviour is a little strange. If so, what's the correct work around? I suppose I could set MSYS2_ARG_CONV_EXCL=* for just that command, but that feels hacky at best. Is there something more permanent I can set in my environment that will work for "all" commands?

Start with the minimal xmllint reproduction in the issue and compare the path-conversion behavior introduced by #143. The payload names no source files or tests; done means determining whether the quoted XPath behavior is intended and fixing it or documenting a supported permanent workaround.
