githelp on a single command should succeed
$ hg githelp -- commit
hg commit
$ hg githelp -- git commit
hg commit
githelp should fail nicely if we don't give it arguments
$ hg githelp
abort: missing git command - usage: hg githelp -- <git command>

$ hg githelp -- git
abort: missing git command - usage: hg githelp -- <git command>

githelp on a command with options should succeed
$ hg githelp -- commit -pm "abc"
hg commit --interactive -m 'abc'
githelp on a command with standalone unrecognized option should succeed with warning
$ hg githelp -- commit -p -v
ignoring unknown option -v
hg commit --interactive
githelp on a command with unrecognized option packed with other options should fail with error
$ hg githelp -- commit -pv
abort: unknown option 'v' packed with other options
(please try passing the option as its own flag: -v)
