bash_completion: small optimization Right now we always call "hg help $cmd" to get the canonical name of $cmd (i.e. to go from "co" to "update"). This patch optimistically assumes that $cmd is already the canonical form and tries to generate completions for it. If that fails, it falls back to canonicalizing $cmd and trying again. This means that: - if a command or alias is explicitly handled by the _hg_command_specific function, things get somewhat faster - as long as the canonical $cmd is handled by _hg_command_specific, all its aliases and abbreviations are also handled.
