bash_completion: be more careful about whitespaces
- use awk to parse the output of hg help.
- print one completion candidate per line
- print the debug commands after regular commands
(this eases the shell side of the parsing)
- don't print aliases that are simple abbreviations
(e.g. up/update, id/identify)
