I wanted to do this too but:
- They behave differently, in my case hgexecutable() == 'c:\python25\scripts\hg.bat' while hgcmd() == ['c:\python25\python.exe', 'c:\python25\scripts\hg']
- hgcmd() returns multiple parameters, that's hard to reconciliate with hgexecutable() and $HG without escaping them as a command line, which would make the whole spawndetached() thing harder to implement.
