revert c191ed664f6c437ebc3e0c859c53e48b445401f1
'got ref' should only work with naked ref names; implicitly putting things into 'refs/heads' is a job for something like a 'got branch' command.
got commit can't use unveil with an editor
Theo says unveil(2) is supposed to traverse exec(2) (though this seems to be broken or not implemented at present). In which case the commmit message editor would find itself without access to files it needs (startup config files, shared libs, user's home dir, etc.) Apply unveil after the log message has been written.
make 'got commit' look up EDITOR in PATH
The previous code only worked if EDITOR contained an absolute path.
tog: don't clear diff view contents when indicating diff progress
this is much easier on the eyes when moving through diffs
