Apparently mach try (at least when I just tried it as "mach try --preset=something") spews the output of "hg status" to the terminal. In my case that's over 100 lines of .rej/.orig files and whatnot, plus various other noise from things that like to dump files in the srcdir. It would be really nice to not have this noise there.

Looks like this only happens for mach try fuzzy, not mach try syntax?

I think we should fix this by converting `mach try` to use the mozversioncontrol Python package for doing VCS interaction. I /think/ there's an open bug on that somewhere...

This comes from the `push-to-try` extension, so this is a bug in version-control-tools. Personally I like this behaviour because once in awhile I notice I forgot to add a file and it saves me a wasted try run. However I didn't realize .orig and .rej files weren't added to topsrcdir/.hgignore. Is there a reason we don't have those added? Looks like I never noticed this because I have them listed in my ~/.hgignore. As a workaround, you can create ~/.hgignore and add: syntax:glob *.rej *.orig
