test-serve: make the 'listening at *' lines optional
The daemonized serve process doesn't print these lines out (see 448d0c452140).
I was able to get it to with the following hack:
diff --git a/mercurial/win32.py b/mercurial/win32.py
--- a/mercurial/win32.py
+++ b/mercurial/win32.py

+ creationflags=subprocess.CREATE_NEW_PROCESS_GROUP).pid
+
# No standard library function really spawns a fully detached
# process under win32 because they allocate pipes or other objects
# to handle standard streams communications. Passing these objects
However, MSYS translates --prefixes starting with '/' to 'C:/MinGW/msys/1.0',
which changes the output. The output isn't so important that I want to spend a
bunch of time on this, and risk breaking some subtle behavior of `hg serve -d`
with the more complicated code.
