Subject: MinGW: Report errors when failing to launch the html browser.
X-Git-Tag: v1.7.4-rc0~193^2~11

MinGW: Report errors when failing to launch the html browser.

The mingw function to launch the system html browser is silent if the
target file does not exist leaving the user confused. Make it display
something.
