Only look up tags and branches as a last resort

hgweb: add heads to gitweb summary

zsh: cache hg help output

zsh: complete according to the -R option if specified

zsh: add view opts

zsh: add --style and --template opts

zsh: add -r to parents

zsh: expand tags lazily

make mq play nicely with the branch cache - if no patches are applied, don't do anything different - if the cache includes valid data from one of the patch revisions, use the cache, but don't save anything new - if the cache has data from before the patch revisions only, save what the list of branches would be without the patch revisions

Split branchtags into two additional functions. This makes it easier to override only parts of the cache saving process.

Commit username: Better error message, abort on empty name, fix documentation.

hgweb: make #motd# available for all templates

zsh completion: basic mq support

bash_completion: qguard

bash_completion: allow overriding completion for arguments that start with "-"

bash_completion: qfold, qrename, qheader, qclone and qselect

bash_completion: email --bcc

bash_completion: qdelete --rev

bash_completion: make export fall back to tags when there's no mq patch applied

bash_completion: don't complete export with "garbage" when mq is not around The "garbage" is the output of hg help printed when a command is not found.

Fix "templater object got multiple values for keyword argument 'motd'" caused by adding motd to the call to the index template (2896ce093ec4)

Add #motd# to gitweb pages. Needs to pass self.motd to index template, too.

gitweb: add revision numbers to annotate changeset links

gitweb: add revision numbers to filerevision changeset links

hgweb: add revision numbers to changeset parent/child links
